+    This is the configuration class to store the configuration of a [`SiglipTextModel`]. It is used to instantiate a
+    Siglip text encoder according to the specified arguments, defining the model architecture. Instantiating a
+    configuration with the defaults will yield a similar configuration to that of the text encoder of the Siglip

+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the

+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 32000):
+            Vocabulary size of the Siglip text model. Defines the number of different tokens that can be represented by
+            the `inputs_ids` passed when calling [`SiglipModel`].
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimensionality of the encoder layers and the pooler layer.
+        intermediate_size (`int`, *optional*, defaults to 3072):
+            Dimensionality of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        max_position_embeddings (`int`, *optional*, defaults to 64):
+            The maximum sequence length that this model might ever be used with. Typically set this to something large
+            just in case (e.g., 512 or 1024 or 2048).
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu_pytorch_tanh"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"selu"` and `"gelu_new"` `"quick_gelu"` are supported.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-06):
+            The epsilon used by the layer normalization layers.
+        attention_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        pad_token_id (`int`, *optional*, defaults to 1):
+            The id of the padding token in the vocabulary.
+        bos_token_id (`int`, *optional*, defaults to 49406):
+            The id of the beginning-of-sequence token in the vocabulary.

+
+    This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to
+    this superclass for more information regarding those methods.

+        vocab_file (`str`):
+            [SentencePiece](https://github.com/google/sentencepiece) file (generally has a *.spm* extension) that
+            contains the vocabulary necessary to instantiate a tokenizer.

+            The end of sequence token.
+        unk_token (`str`, *optional*, defaults to `"<unk>"`):
+            The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
+            token instead.
+        pad_token (`str`, *optional*, defaults to `"</s>"`):
+            The token used for padding, for example when batching sequences of different lengths.
+        additional_special_tokens (`List[str]`, *optional*):
+            Additional special tokens used by the tokenizer.
+        sp_model_kwargs (`dict`, *optional*):
+            Will be passed to the `SentencePieceProcessor.__init__()` method. The [Python wrapper for
+            SentencePiece](https://github.com/google/sentencepiece/tree/master/python) can be used, among other things,

+              - `nbest_size > 1`: samples from the nbest_size results.
+              - `nbest_size < 0`: assuming that nbest_size is infinite and samples from the all hypothesis (lattice)
+                using forward-filtering-and-backward-sampling algorithm.
+
+            - `alpha`: Smoothing parameter for unigram sampling, and dropout probability of merge operations for
+              BPE-dropout.
+        model_max_length (`int`, *optional*, defaults to 64):
+            The maximum length (in number of tokens) for model inputs.
+        do_lower_case (`bool`, *optional*, defaults to `True`):

+    This is the configuration class to store the configuration of a [`Siglip2VisionModel`]. It is used to instantiate a
+    Siglip2 vision encoder according to the specified arguments, defining the model architecture. Instantiating a
+    configuration with the defaults will yield a similar configuration to that of the vision encoder of the Siglip2
+    [google/siglip2-base-patch16-naflex](https://huggingface.co/google/siglip2-base-patch16-naflex) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimensionality of the encoder layers and the pooler layer.
+        intermediate_size (`int`, *optional*, defaults to 3072):
+            Dimensionality of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        num_channels (`int`, *optional*, defaults to 3):
+            Number of channels in the input images.
+        num_patches (`int`, *optional*, defaults to 256):
+            The number of patches in the image with the size of (`patch_size`, `patch_size`).
+            The image is resized to fill maximum of this number of patches, and to preserve
+            the aspect ratio. In case the resulted number of patches is lower, the image is
+            padded in "patch" dimension.
+        patch_size (`int`, *optional*, defaults to 16):
+            The size (resolution) of each patch.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu_pytorch_tanh"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"selu"` and `"gelu_new"` `"quick_gelu"` are supported.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-06):
+            The epsilon used by the layer normalization layers.
+        attention_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.

+        of the above two methods for more information.

+                  acceptable input length for the model if that argument is not provided.
+                - `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single
+                  sequence if provided).
+                - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different
+                  lengths).
+            max_length (`int`, *optional*, defaults to 64):
+                Maximum length of the returned list and optionally padding length (see above).
+            truncation (`bool`, *optional*, defaults to `True`):
+                Activates truncation to cut input sequences longer than `max_length` to `max_length`.

+                If set, will return tensors of a particular framework. Acceptable values are:

+              `None`).
+            - **pixel_values** -- Pixel values to be fed to a model. Returned when `images` is not `None`.

+        - The text token sequence is: `tok_1 tok_2 tok_3 <fake_token_around_image> <image> <image> ... <image> <fake_token_around_image> tok_4`.
+        - We get the image hidden states for the image through the vision encoder and that hidden state, after a pixel shuffle operation, is then projected into the text embedding space.
+        We thus have a sequence of image hidden states of size (1, image_seq_len, hidden_dim), where 1 is for batch_size of 1 image and hidden_dim is the hidden_dim of the LM transformer.
+        - The merging happens so that we obtain the following sequence: `vector_tok_1 vector_tok_2 vector_tok_3 vector_fake_tok_around_image {sequence of image_seq_len image hidden states} vector_fake_toke_around_image vector_tok_4`. That sequence is fed to the LM.
+        - To fit the format of that sequence, `input_ids`, `input_embeds`, `attention_mask` are all 3 adapted to insert the image hidden states.

+SPEECH_ENCODER_DECODER_START_DOCSTRING = r"""
+    This class can be used to initialize a speech-sequence-to-text-sequence model with any pretrained speech
+    autoencoding model as the encoder and any pretrained text autoregressive model as the decoder. The encoder is
+    loaded via [`~AutoModel.from_pretrained`] function and the decoder is loaded via
+    [`~AutoModelForCausalLM.from_pretrained`] function. Cross-attention layers are automatically added to the decoder
+    and should be fine-tuned on a downstream generative task, like summarization.
+
+    The effectiveness of initializing sequence-to-sequence models with pretrained checkpoints for sequence generation
+    tasks was shown in [Leveraging Pre-trained Checkpoints for Sequence Generation
+    Tasks](https://arxiv.org/abs/1907.12461) by Sascha Rothe, Shashi Narayan, Aliaksei Severyn. Michael Matena, Yanqi
+    Zhou, Wei Li, Peter J. Liu.
+
+    Additionally, in [Large-Scale Self- and Semi-Supervised Learning for Speech
+    Translation](https://arxiv.org/abs/2104.06678) it is shown how leveraging large pretrained speech models for speech
+    translation yields a significant performance improvement.
+
+    After such an Speech-Encoder Decoder model has been trained/fine-tuned, it can be saved/loaded just like any other
+    models (see the examples for more information).
+
+    This model inherits from [`FlaxPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a Flax Linen
+    [flax.nn.Module](https://flax.readthedocs.io/en/latest/_autosummary/flax.nn.module.html) subclass. Use it as a
+    regular Flax Module and refer to the Flax documentation for all matter related to general usage and behavior.
+
+    Parameters:
+        config ([`SpeechEncoderDecoderConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~FlaxPreTrainedModel.from_pretrained`] method to load the model weights.
+        dtype (`jax.numpy.dtype`, *optional*, defaults to `jax.numpy.float32`):
+            The data type of the computation. Can be one of `jax.numpy.float32`, `jax.numpy.float16` (on GPUs) and
+            `jax.numpy.bfloat16` (on TPUs).
+
+            This can be used to enable mixed-precision training or half-precision inference on GPUs or TPUs. If
+            specified all the computation will be performed with the given `dtype`.
+
+            **Note that this only specifies the dtype of the computation and does not influence the dtype of model
+            parameters.**
+
+            If you wish to change the dtype of the model parameters, see [`~FlaxPreTrainedModel.to_fp16`] and
+            [`~FlaxPreTrainedModel.to_bf16`].

+    tasks was shown in [Leveraging Pre-trained Checkpoints for Sequence Generation
+    Tasks](https://arxiv.org/abs/1907.12461) by Sascha Rothe, Shashi Narayan, Aliaksei Severyn. Michael Matena, Yanqi
+    Zhou, Wei Li, Peter J. Liu.
+
+    Additionally, in [Large-Scale Self- and Semi-Supervised Learning for Speech
+    Translation](https://arxiv.org/abs/2104.06678) it is shown how leveraging large pretrained speech models for speech
+    translation yields a significant performance improvement.
+
+    After such an Speech-Encoder Decoder model has been trained/fine-tuned, it can be saved/loaded just like any other
+    models (see the examples for more information).
+
+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass.
+    Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
+    and behavior.
+
+    Parameters:
+        config ([`SpeechEncoderDecoderConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+    Args:
+        inputs (`torch.FloatTensor` of shape `(batch_size, sequence_length)` or `(batch_size, sequence_length, feature_dim)`, *optional*):
+            Float values of input raw speech waveform or speech features. Values can be obtained by loading a `.flac`
+            or `.wav` audio file into an array of type `List[float]` or a `numpy.ndarray`, *e.g.* via the soundfile
+            library (`pip install soundfile`). To prepare the array into `inputs`, either the [`Wav2Vec2Processor`] or
+            [`Speech2TextProcessor`] should be used for padding and conversion into a tensor of type
+            `torch.FloatTensor`.
+        attention_mask (`torch.FloatTensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
+
+            - 1 for tokens that are **not masked**,
+            - 0 for tokens that are **masked**.
+
+            [What are attention masks?](../glossary#attention-mask)
+        decoder_input_ids (`torch.LongTensor` of shape `(batch_size, target_sequence_length)`, *optional*):
+            Indices of decoder input sequence tokens in the vocabulary.
+
+            Indices can be obtained using [`PreTrainedTokenizer`]. See [`PreTrainedTokenizer.encode`] and
+            [`PreTrainedTokenizer.__call__`] for details.
+
+            [What are input IDs?](../glossary#input-ids)
+
+            If `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
+            `past_key_values`).
+
+            For training, `decoder_input_ids` are automatically created by the model by shifting the `labels` to the
+            right, replacing -100 by the `pad_token_id` and prepending them with the `decoder_start_token_id`.
+        decoder_attention_mask (`torch.BoolTensor` of shape `(batch_size, target_sequence_length)`, *optional*):
+            Default behavior: generate a tensor that ignores pad tokens in `decoder_input_ids`. Causal mask will also
+            be used by default.
+        encoder_outputs (`tuple(torch.FloatTensor)`, *optional*):
+            This tuple must consist of (`last_hidden_state`, *optional*: `hidden_states`, *optional*: `attentions`)
+            `last_hidden_state` (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`) is a tensor
+            of hidden-states at the output of the last layer of the encoder. Used in the cross-attention of the
+            decoder.
+        past_key_values (`tuple(tuple(torch.FloatTensor))` of length `config.n_layers` with each tuple having 4 tensors of shape `(batch_size, num_heads, sequence_length - 1, embed_size_per_head)`):
+            Contains precomputed key and value hidden states of the attention blocks. Can be used to speed up decoding.
+
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
+            don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all
+            `decoder_input_ids` of shape `(batch_size, sequence_length)`.
+        inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
+            model's internal embedding lookup matrix.
+        decoder_inputs_embeds (`torch.FloatTensor` of shape `(batch_size, target_sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `decoder_input_ids` you can choose to directly pass an embedded
+            representation. This is useful if you want more control over how to convert `decoder_input_ids` indices
+            into associated vectors than the model's internal embedding lookup matrix.
+        labels (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Labels for computing the masked language modeling loss for the decoder. Indices should be in `[-100, 0,
+            ..., config.vocab_size]` (see `input_ids` docstring) Tokens with indices set to `-100` are ignored
+            (masked), the loss is only computed for the tokens with labels in `[0, ..., config.vocab_size]`
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+            `past_key_values`).
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail.
+        input_values (`torch.FloatTensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Float values of input raw speech waveform. Values can be obtained by loading a *.flac* or *.wav* audio file
+            into an array of type *List[float]* or a *numpy.ndarray*, *e.g.* via the soundfile library (*pip install
+            soundfile*). To prepare the array into *input_values*, the [`Wav2Vec2Processor`] should be used for padding
+            and conversion into a tensor of type *torch.FloatTensor*. See [`Wav2Vec2Processor.__call__`] for details.
+        input_features (`torch.FloatTensor` of shape `(batch_size, sequence_length, feature_size)`, *optional*):
+            Float values of fbank features extracted from the raw speech waveform. Raw speech waveform can be obtained
+            by loading a `.flac` or `.wav` audio file into an array of type `List[float]` or a `numpy.ndarray`, *e.g.*
+            via the soundfile library (`pip install soundfile`). To prepare the array into `input_features`, the
+            [`Speech2TextFeatureExtractor`] should be used for extracting the fbank features, padding and conversion
+            into a tensor of type `torch.FloatTensor`. See [`~Speech2TextFeatureExtractor.__call__`]
+        return_dict (`bool`, *optional*):
+            If set to `True`, the model will return a [`~utils.Seq2SeqLMOutput`] instead of a plain tuple.
+        kwargs (*optional*): Remaining dictionary of keyword arguments. Keyword arguments come in two flavors:
+
+            - Without a prefix which will be input as `**encoder_kwargs` for the encoder forward function.
+            - With a *decoder_* prefix which will be input as `**decoder_kwargs` for the decoder forward function.

+class Speech2TextConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`Speech2TextModel`]. It is used to instantiate a
+    Speech2Text model according to the specified arguments, defining the model architecture. Instantiating a
+    configuration with the defaults will yield a similar configuration to that of the Speech2Text
+    [facebook/s2t-small-librispeech-asr](https://huggingface.co/facebook/s2t-small-librispeech-asr) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 10000):
+            Vocabulary size of the Speech2Text model. Defines the number of different tokens that can be represented by

+            more details.
+        decoder_layerdrop (`float`, *optional*, defaults to 0.0):
+            The LayerDrop probability for the decoder. See the [LayerDrop paper](https://arxiv.org/abs/1909.11556) for
+            more details.
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether the model should return the last key/values attentions (not used by all models).
+        is_encoder_decoder (`bool`, *optional*, defaults to `True`):
+            Whether the model is set up as an encoder-decoder architecture for sequence-to-sequence tasks.
+        activation_function (`str` or `function`, *optional*, defaults to `"relu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"silu"` and `"gelu_new"` are supported.
+        d_model (`int`, *optional*, defaults to 256):
+            Dimensionality of the layers and the pooler layer.

+            The maximum sequence length of log-mel filter-bank features that this model might ever be used with.
+        max_target_positions (`int`, *optional*, defaults to 1024):
+            The maximum sequence length that this model might ever be used with. Typically, set this to something large
+            just in case (e.g., 512 or 1024 or 2048).
+        num_conv_layers (`int`, *optional*, defaults to 2):

+        conv_channels (`int`, *optional*, defaults to 1024):
+            An integer defining the number of output channels of each convolution layers except the final one in the

+    Constructs a Speech2Text feature extractor.
+
+    This feature extractor inherits from [`Speech2TextFeatureExtractor`] which contains most of the main methods. Users
+    should refer to this superclass for more information regarding those methods.
+
+    This class extracts mel-filter bank features from raw speech using TorchAudio if installed or using numpy
+    otherwise, and applies utterance-level cepstral mean and variance normalization to the extracted features.
+
+    Args:
+        feature_size (`int`, *optional*, defaults to 80):
+            The feature dimension of the extracted features.
+        sampling_rate (`int`, *optional*, defaults to 16000):
+            The sampling rate at which the audio files should be digitalized expressed in hertz (Hz).
+        num_mel_bins (`int`, *optional*, defaults to 80):
+            Number of Mel-frequency bins.
+        padding_value (`float`, *optional*, defaults to 0.0):
+            The value that is used to fill the padding vectors.
+        dither (`float`, *optional*, defaults to 0.0):
+            Adds dithering. In other words, adds a small Gaussian noise to each frame.
+            E.g. use 4.0 to add dithering with a normal distribution centered
+            around 0.0 with standard deviation 4.0 (assuming [-32k,+32k] range of kaldi waveform).
+            The value 0.0 means no dithering.
+            Dithering has similar effect as `mel_floor`. It reduces the high log_mel_fbank
+            values for signals with hard-zero sections, when VAD cutoff is present in the signal.
+        do_ceptral_normalize (`bool`, *optional*, defaults to `True`):
+            Whether or not to apply utterance-level cepstral mean and variance normalization to extracted features.
+        normalize_means (`bool`, *optional*, defaults to `True`):
+            Whether or not to zero-mean normalize the extracted features.
+        normalize_vars (`bool`, *optional*, defaults to `True`):
+            Whether or not to unit-variance normalize the extracted features.

+                The sequence or batch of sequences to be padded. Each sequence can be a numpy array, a list of float

+                index) among:
+
+                - `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single
+                  sequence if provided).
+                - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum
+                  acceptable input length for the model if that argument is not provided.
+                - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different
+                  lengths).
+            max_length (`int`, *optional*):
+                Maximum length of the returned list and optionally padding length (see above).
+            truncation (`bool`):
+                Activates truncation to cut input sequences longer than *max_length* to *max_length*.
+            pad_to_multiple_of (`int`, *optional*):
+                If set will pad the sequence to a multiple of the provided value.
+
+                This is especially useful to enable the use of Tensor Cores on NVIDIA hardware with compute capability
+                `>= 7.5` (Volta), or on TPUs which benefit from having sequence lengths be a multiple of 128.
+            return_attention_mask (`bool`, *optional*):
+                Whether to return the attention mask. If left to the default, will return the attention mask according
+                to the specific feature_extractor's default.
+
+                [What are attention masks?](../glossary#attention-mask)
+
+                <Tip>
+
+                For Speech2TextTransformer models, `attention_mask` should always be passed for batched inference, to

+
+            Indices can be obtained using [`SpeechToTextTokenizer`]. See [`PreTrainedTokenizer.encode`] and

+
+            [What are decoder input IDs?](../glossary#decoder-input-ids)
+
+            SpeechToText uses the `eos_token_id` as the starting token for `decoder_input_ids` generation. If
+            `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see

+            Default behavior: generate a tensor that ignores pad tokens in `decoder_input_ids`. Causal mask will also
+            be used by default.
+
+            If you want to change padding behavior, you should read
+            [`modeling_speech_to_text._prepare_decoder_attention_mask`] and modify to your needs. See diagram 1 in [the

+        head_mask (`torch.Tensor` of shape `(encoder_layers, encoder_attention_heads)`, *optional*):
+            Mask to nullify selected heads of the attention modules in the encoder. Mask values selected in `[0, 1]`:
+
+            - 1 indicates the head is **not masked**,

+            `last_hidden_state` of shape `(batch_size, sequence_length, hidden_size)`, *optional*) is a sequence of
+            hidden-states at the output of the last layer of the encoder. Used in the cross-attention of the decoder.
+        past_key_values (`tuple(tuple(torch.FloatTensor))`, *optional*, returned when `use_cache=True` is passed or when `config.use_cache=True`):
+            Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of shape
+            `(batch_size, num_heads, sequence_length, embed_size_per_head)`) and 2 additional tensors of shape
+            `(batch_size, num_heads, encoder_sequence_length, embed_size_per_head)`.
+
+            Contains pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention
+            blocks) that can be used (see `past_key_values` input) to speed up sequential decoding.
+
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
+            don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all

+            Optionally, instead of passing `decoder_input_ids` you can choose to directly pass an embedded
+            representation. If `past_key_values` is used, optionally only the last `decoder_inputs_embeds` have to be

+    This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the

+    etc.)
+
+    This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it
+    as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and
+    behavior.
+
+    <Tip>
+
+    TensorFlow models and layers in `transformers` accept two formats as input:
+
+    - having all inputs as keyword arguments (like PyTorch models), or
+    - having all inputs as a list, tuple or dict in the first positional argument.
+
+    The reason the second format is supported is that Keras methods prefer this format when passing inputs to models
+    and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just
+    pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second
+    format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with
+    the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first
+    positional argument:
+
+    - a single Tensor with `input_ids` only and nothing else: `model(input_ids)`
+    - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
+    `model([input_ids, attention_mask])` or `model([input_ids, attention_mask, token_type_ids])`
+    - a dictionary with one or several input Tensors associated to the input names given in the docstring:
+    `model({"input_ids": input_ids, "token_type_ids": token_type_ids})`
+
+    Note that when creating models and layers with
+    [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry
+    about any of this, as you can just pass inputs like you would to any other Python function!

+        input_features (`tf.Tensor` of shape `(batch_size, sequence_length, feature_size)`):
+            Float values of fbank features extracted from the raw speech waveform. Raw speech waveform can be obtained
+            by loading a `.flac` or `.wav` audio file into an array of type `List[float]` or a `numpy.ndarray`, *e.g.*
+            via the soundfile library (`pip install soundfile`). To prepare the array into `input_features`, the

+            tensor of floats. See [`~Speech2TextFeatureExtractor.__call__`]
+        attention_mask (`tf.Tensor` of shape `({0})`, *optional*):

+
+            - 1 for tokens that are **not masked**,

+
+            Indices can be obtained using [`Speech2TextTokenizer`]. See [`PreTrainedTokenizer.encode`] and
+            [`PreTrainedTokenizer.__call__`] for details.
+
+            [What are decoder input IDs?](../glossary#decoder-input-ids)
+
+            SpeechToText uses the `eos_token_id` as the starting token for `decoder_input_ids` generation. If
+            `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
+            `past_key_values`).
+
+            For translation and summarization training, `decoder_input_ids` should be provided. If no
+            `decoder_input_ids` is provided, the model will create this tensor by shifting the `input_ids` to the right
+            for denoising pre-training following the paper.
+        decoder_attention_mask (`tf.Tensor` of shape `(batch_size, target_sequence_length)`, *optional*):
+            will be made by default and ignore pad tokens. It is not recommended to set this for most use cases.
+        head_mask (`tf.Tensor` of shape `(encoder_layers, encoder_attention_heads)`, *optional*):
+            Mask to nullify selected heads of the attention modules in the encoder. Mask values selected in `[0, 1]`:
+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
+
+        decoder_head_mask (`tf.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, *optional*):
+            Mask to nullify selected heads of the attention modules in the decoder. Mask values selected in `[0, 1]`:
+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
+
+        cross_attn_head_mask (`tf.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, *optional*):
+            Mask to nullify selected heads of the cross-attention modules. Mask values selected in `[0, 1]`:
+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
+
+        encoder_outputs (`tf.FloatTensor`, *optional*):
+            hidden states at the output of the last layer of the encoder. Used in the cross-attention of the decoder.
+            of shape `(batch_size, sequence_length, hidden_size)` is a sequence of
+        past_key_values (`Tuple[Tuple[tf.Tensor]]` of length `config.n_layers`)
+            contains precomputed key and value hidden states of the attention blocks. Can be used to speed up decoding.
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
+            don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all
+            `decoder_input_ids` of shape `(batch_size, sequence_length)`.
+        decoder_inputs_embeds (`tf.FloatTensor` of shape `(batch_size, target_sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `decoder_input_ids` you can choose to directly pass an embedded
+            representation. If `past_key_values` is used, optionally only the last `decoder_inputs_embeds` have to be
+            input (see `past_key_values`). This is useful if you want more control over how to convert
+            `decoder_input_ids` indices into associated vectors than the model's internal embedding lookup matrix.
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+            `past_key_values`).
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail. This argument can be used only in eager mode, in graph mode the value in the

+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail. This argument can be used only in eager mode, in graph mode the value in the config will be

+class SpeechT5HifiGanConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`SpeechT5HifiGanModel`]. It is used to instantiate
+    a SpeechT5 HiFi-GAN vocoder model according to the specified arguments, defining the model architecture.
+    Instantiating a configuration with the defaults will yield a similar configuration to that of the SpeechT5
+    [microsoft/speecht5_hifigan](https://huggingface.co/microsoft/speecht5_hifigan) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        model_in_dim (`int`, *optional*, defaults to 80):
+            The number of frequency bins in the input log-mel spectrogram.
+        sampling_rate (`int`, *optional*, defaults to 16000):
+            The sampling rate at which the output audio will be generated, expressed in hertz (Hz).
+        upsample_initial_channel (`int`, *optional*, defaults to 512):
+            The number of input channels into the upsampling network.
+        upsample_rates (`Tuple[int]` or `List[int]`, *optional*, defaults to `[4, 4, 4, 4]`):
+            A tuple of integers defining the stride of each 1D convolutional layer in the upsampling network. The
+            length of *upsample_rates* defines the number of convolutional layers and has to match the length of
+            *upsample_kernel_sizes*.
+        upsample_kernel_sizes (`Tuple[int]` or `List[int]`, *optional*, defaults to `[8, 8, 8, 8]`):
+            A tuple of integers defining the kernel size of each 1D convolutional layer in the upsampling network. The
+            length of *upsample_kernel_sizes* defines the number of convolutional layers and has to match the length of
+            *upsample_rates*.
+        resblock_kernel_sizes (`Tuple[int]` or `List[int]`, *optional*, defaults to `[3, 7, 11]`):
+            A tuple of integers defining the kernel sizes of the 1D convolutional layers in the multi-receptive field
+            fusion (MRF) module.
+        resblock_dilation_sizes (`Tuple[Tuple[int]]` or `List[List[int]]`, *optional*, defaults to `[[1, 3, 5], [1, 3, 5], [1, 3, 5]]`):
+            A nested tuple of integers defining the dilation rates of the dilated 1D convolutional layers in the
+            multi-receptive field fusion (MRF) module.
+        initializer_range (`float`, *optional*, defaults to 0.01):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        leaky_relu_slope (`float`, *optional*, defaults to 0.1):
+            The angle of the negative slope used by the leaky ReLU activation.
+        normalize_before (`bool`, *optional*, defaults to `True`):
+            Whether or not to normalize the spectrogram before vocoding using the vocoder's learned mean and variance.
+
+    Example:
+
+    ```python
+    >>> from transformers import SpeechT5HifiGan, SpeechT5HifiGanConfig
+
+    >>> # Initializing a "microsoft/speecht5_hifigan" style configuration
+    >>> configuration = SpeechT5HifiGanConfig()
+

+class SpeechT5FeatureExtractor(SequenceFeatureExtractor):
+    r"""
+    Constructs a SpeechT5 feature extractor.
+
+    This class can pre-process a raw speech signal by (optionally) normalizing to zero-mean unit-variance, for use by
+    the SpeechT5 speech encoder prenet.
+
+    This class can also extract log-mel filter bank features from raw speech, for use by the SpeechT5 speech decoder
+    prenet.
+
+    This feature extractor inherits from [`~feature_extraction_sequence_utils.SequenceFeatureExtractor`] which contains
+    most of the main methods. Users should refer to this superclass for more information regarding those methods.
+
+    Args:
+        feature_size (`int`, *optional*, defaults to 1):
+            The feature dimension of the extracted features.
+        sampling_rate (`int`, *optional*, defaults to 16000):
+            The sampling rate at which the audio files should be digitalized expressed in hertz (Hz).
+        padding_value (`float`, *optional*, defaults to 0.0):
+            The value that is used to fill the padding values.
+        do_normalize (`bool`, *optional*, defaults to `False`):
+            Whether or not to zero-mean unit-variance normalize the input. Normalizing can help to significantly
+            improve the performance for some models.
+        num_mel_bins (`int`, *optional*, defaults to 80):
+            The number of mel-frequency bins in the extracted spectrogram features.
+        hop_length (`int`, *optional*, defaults to 16):
+            Number of ms between windows. Otherwise referred to as "shift" in many papers.
+        win_length (`int`, *optional*, defaults to 64):
+            Number of ms per window.
+        win_function (`str`, *optional*, defaults to `"hann_window"`):
+            Name for the window function used for windowing, must be accessible via `torch.{win_function}`
+        frame_signal_scale (`float`, *optional*, defaults to 1.0):
+            Constant multiplied in creating the frames before applying DFT. This argument is deprecated.
+        fmin (`float`, *optional*, defaults to 80):
+            Minimum mel frequency in Hz.
+        fmax (`float`, *optional*, defaults to 7600):
+            Maximum mel frequency in Hz.
+        mel_floor (`float`, *optional*, defaults to 1e-10):
+            Minimum value of mel frequency banks.
+        reduction_factor (`int`, *optional*, defaults to 2):
+            Spectrogram length reduction factor. This argument is deprecated.
+        return_attention_mask (`bool`, *optional*, defaults to `True`):
+            Whether or not [`~SpeechT5FeatureExtractor.__call__`] should return `attention_mask`.

+            audio (`np.ndarray`, `List[float]`, `List[np.ndarray]`, `List[List[float]]`, *optional*):
+                The sequence or batch of sequences to be processed. Each sequence can be a numpy array, a list of float
+                values, a list of numpy arrays or a list of list of float values. This outputs waveform features. Must
+                be mono channel audio, not stereo, i.e. single float per timestep.

+                The sequence or batch of sequences to be processed as targets. Each sequence can be a numpy array, a

+                spectrogram features.
+            padding (`bool`, `str` or [`~utils.PaddingStrategy`], *optional*, defaults to `False`):

+                index) among:
+
+                - `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single
+                  sequence if provided).
+                - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum
+                  acceptable input length for the model if that argument is not provided.
+                - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different
+                  lengths).
+            max_length (`int`, *optional*):
+                Maximum length of the returned list and optionally padding length (see above).
+            truncation (`bool`):
+                Activates truncation to cut input sequences longer than *max_length* to *max_length*.

+
+                This is especially useful to enable the use of Tensor Cores on NVIDIA hardware with compute capability

+            return_attention_mask (`bool`, *optional*):
+                Whether to return the attention mask. If left to the default, will return the attention mask according
+                to the specific feature_extractor's default.

+                - `'np'`: Return Numpy `np.ndarray` objects.

+
+            If you want to change padding behavior, you should read [`SpeechT5Decoder._prepare_decoder_attention_mask`]

+    This is the configuration class to store the configuration of a [`SplinterModel`]. It is used to instantiate an
+    Splinter model according to the specified arguments, defining the model architecture. Instantiating a configuration
+    with the defaults will yield a similar configuration to that of the Splinter
+    [tau/splinter-base](https://huggingface.co/tau/splinter-base) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 30522):
+            Vocabulary size of the Splinter model. Defines the number of different tokens that can be represented by
+            the `inputs_ids` passed when calling [`SplinterModel`].
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimension of the encoder layers and the pooler layer.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        intermediate_size (`int`, *optional*, defaults to 3072):
+            Dimension of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"selu"` and `"gelu_new"` are supported.
+        hidden_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout ratio for the attention probabilities.

+    Construct a Splinter tokenizer. Based on WordPiece.
+
+    This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to
+    this superclass for more information regarding those methods.
+
+    Args:
+        vocab_file (`str`):
+            File containing the vocabulary.
+        do_lower_case (`bool`, *optional*, defaults to `True`):
+            Whether or not to lowercase the input when tokenizing.
+        do_basic_tokenize (`bool`, *optional*, defaults to `True`):
+            Whether or not to do basic tokenization before WordPiece.
+        never_split (`Iterable`, *optional*):
+            Collection of tokens which will never be split during tokenization. Only has an effect when
+            `do_basic_tokenize=True`
+        unk_token (`str`, *optional*, defaults to `"[UNK]"`):
+            The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
+            token instead.
+        sep_token (`str`, *optional*, defaults to `"[SEP]"`):
+            The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for
+            sequence classification or for a text and a question for question answering. It is also used as the last
+            token of a sequence built with special tokens.
+        pad_token (`str`, *optional*, defaults to `"[PAD]"`):
+            The token used for padding, for example when batching sequences of different lengths.
+        cls_token (`str`, *optional*, defaults to `"[CLS]"`):
+            The classifier token which is used when doing sequence classification (classification of the whole sequence
+            instead of per-token classification). It is the first token of the sequence when built with special tokens.
+        mask_token (`str`, *optional*, defaults to `"[MASK]"`):
+            The token used for masking values. This is the token used when training this model with masked language
+            modeling. This is the token which the model will try to predict.
+        question_token (`str`, *optional*, defaults to `"[QUESTION]"`):
+            The token used for constructing question representations.
+        tokenize_chinese_chars (`bool`, *optional*, defaults to `True`):
+            Whether or not to tokenize Chinese characters.
+
+            This should likely be deactivated for Japanese (see this
+            [issue](https://github.com/huggingface/transformers/issues/328)).

+        cls_token (`str`, *optional*, defaults to `"[CLS]"`):
+            The classifier token which is used when doing sequence classification (classification of the whole sequence
+            instead of per-token classification). It is the first token of the sequence when built with special tokens.
+        mask_token (`str`, *optional*, defaults to `"[MASK]"`):

+        tokenize_chinese_chars (`bool`, *optional*, defaults to `True`):

+    The SqueezeBERT model was proposed in [SqueezeBERT: What can computer vision teach NLP about efficient neural
+    networks?](https://arxiv.org/abs/2006.11316) by Forrest N. Iandola, Albert E. Shaw, Ravi Krishna, and Kurt W.
+    Keutzer
+
+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass.
+    Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
+    and behavior.
+
+    For best results finetuning SqueezeBERT on text classification tasks, it is recommended to use the
+    *squeezebert/squeezebert-mnli-headless* checkpoint as a starting point.
+
+    Parameters:
+        config ([`SqueezeBertConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+    Construct a SqueezeBERT tokenizer. Based on WordPiece.
+
+    This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to
+    this superclass for more information regarding those methods.
+
+    Args:
+        vocab_file (`str`):
+            File containing the vocabulary.
+        do_lower_case (`bool`, *optional*, defaults to `True`):
+            Whether or not to lowercase the input when tokenizing.
+        do_basic_tokenize (`bool`, *optional*, defaults to `True`):
+            Whether or not to do basic tokenization before WordPiece.
+        never_split (`Iterable`, *optional*):
+            Collection of tokens which will never be split during tokenization. Only has an effect when
+            `do_basic_tokenize=True`
+        unk_token (`str`, *optional*, defaults to `"[UNK]"`):
+            The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
+            token instead.
+        sep_token (`str`, *optional*, defaults to `"[SEP]"`):
+            The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for
+            sequence classification or for a text and a question for question answering. It is also used as the last
+            token of a sequence built with special tokens.
+        pad_token (`str`, *optional*, defaults to `"[PAD]"`):
+            The token used for padding, for example when batching sequences of different lengths.
+        cls_token (`str`, *optional*, defaults to `"[CLS]"`):
+            The classifier token which is used when doing sequence classification (classification of the whole sequence
+            instead of per-token classification). It is the first token of the sequence when built with special tokens.
+        mask_token (`str`, *optional*, defaults to `"[MASK]"`):
+            The token used for masking values. This is the token used when training this model with masked language
+            modeling. This is the token which the model will try to predict.
+        tokenize_chinese_chars (`bool`, *optional*, defaults to `True`):
+            Whether or not to tokenize Chinese characters.
+
+            This should likely be deactivated for Japanese (see this
+            [issue](https://github.com/huggingface/transformers/issues/328)).
+        strip_accents (`bool`, *optional*):
+            Whether or not to strip all accents. If this option is not specified, then it will be determined by the
+            value for `lowercase` (as in the original SqueezeBERT).
+        clean_up_tokenization_spaces (`bool`, *optional*, defaults to `True`):
+            Whether or not to cleanup spaces after decoding, cleanup consists in removing potential artifacts like
+            extra spaces.

+    r"""
+    Construct a "fast" SqueezeBERT tokenizer (backed by HuggingFace's *tokenizers* library). Based on WordPiece.
+
+    This tokenizer inherits from [`PreTrainedTokenizerFast`] which contains most of the main methods. Users should
+    refer to this superclass for more information regarding those methods.
+
+    Args:
+        vocab_file (`str`):
+            File containing the vocabulary.
+        do_lower_case (`bool`, *optional*, defaults to `True`):
+            Whether or not to lowercase the input when tokenizing.
+        unk_token (`str`, *optional*, defaults to `"[UNK]"`):
+            The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
+            token instead.
+        sep_token (`str`, *optional*, defaults to `"[SEP]"`):
+            The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for
+            sequence classification or for a text and a question for question answering. It is also used as the last
+            token of a sequence built with special tokens.
+        pad_token (`str`, *optional*, defaults to `"[PAD]"`):
+            The token used for padding, for example when batching sequences of different lengths.
+        cls_token (`str`, *optional*, defaults to `"[CLS]"`):
+            The classifier token which is used when doing sequence classification (classification of the whole sequence
+            instead of per-token classification). It is the first token of the sequence when built with special tokens.
+        mask_token (`str`, *optional*, defaults to `"[MASK]"`):
+            The token used for masking values. This is the token used when training this model with masked language
+            modeling. This is the token which the model will try to predict.
+        clean_text (`bool`, *optional*, defaults to `True`):
+            Whether or not to clean the text before tokenization by removing any control characters and replacing all
+            whitespaces by the classic one.
+        tokenize_chinese_chars (`bool`, *optional*, defaults to `True`):
+            Whether or not to tokenize Chinese characters. This should likely be deactivated for Japanese (see [this
+            issue](https://github.com/huggingface/transformers/issues/328)).
+        strip_accents (`bool`, *optional*):
+            Whether or not to strip all accents. If this option is not specified, then it will be determined by the
+            value for `lowercase` (as in the original SqueezeBERT).
+        wordpieces_prefix (`str`, *optional*, defaults to `"##"`):
+            The prefix for subwords.

+    r"""
+    This is the configuration class to store the configuration of a [`~StableLmModel`].
+    It is used to instantiate an StableLM model according to the specified arguments, defining the model
+    architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of
+    the StableLM [stabilityai/stablelm-3b-4e1t](https://huggingface.co/stabilityai/stablelm-3b-4e1t) architecture.
+
+    Configuration objects inherit from  [`PretrainedConfig`] and can be used
+    to control the model outputs. Read the documentation from  [`PretrainedConfig`]
+    for more information.
+
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 50304):
+            Vocabulary size of the StableLM model. Defines the number of different tokens that
+            can be represented by the `inputs_ids` passed when calling [`StableLmModel`].
+        intermediate_size (`int`, *optional*, defaults to 6912):
+            Dimension of the MLP representations.
+        hidden_size (`int`, *optional*, defaults to 2560):
+            Number of hidden layers in the Transformer decoder.
+        num_hidden_layers (`int`, *optional*, defaults to 32):
+            Number of hidden layers in the Transformer decoder.
+        num_attention_heads (`int`, *optional*, defaults to 32):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        num_key_value_heads (`int`, *optional*, defaults to 32):
+            This is the number of key_value heads that should be used to implement Grouped Query Attention. If
+            `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
+            `num_key_value_heads=1` the model will use Multi Query Attention (MQA) otherwise GQA is used. When
+            converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
+            by meanpooling all the original heads within that group. For more details checkout [this
+            paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to
+            `num_attention_heads`.
+        hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
+            The non-linear activation function (function or string).
+        max_position_embeddings (`int`, *optional*, defaults to 4096):
+            The maximum sequence length that this model might ever be used with.
+            Typically set this to something large just in case (e.g., 512 or 1024 or 2048).
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing
+             all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-05):
+            The epsilon used by the normalization layers.
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should return the last key/values attentions
+            (not used by all models). Only relevant if `config.is_decoder=True`.
+        tie_word_embeddings (`bool`, *optional*, defaults to `False`):
+            Whether the model's input and output word embeddings should be tied.

+            The base period of the RoPE embeddings.
+        rope_scaling (`Dict`, *optional*):
+            Dictionary containing the scaling configuration for the RoPE embeddings. NOTE: if you apply new rope type
+            and you expect the model to work on longer `max_position_embeddings`, we recommend you to update this value
+            accordingly.
+            Expected contents:
+                `rope_type` (`str`):
+                    The sub-variant of RoPE to use. Can be one of ['default', 'linear', 'dynamic', 'yarn', 'longrope',
+                    'llama3'], with 'default' being the original RoPE implementation.
+                `factor` (`float`, *optional*):
+                    Used with all rope types except 'default'. The scaling factor to apply to the RoPE embeddings. In
+                    most scaling types, a `factor` of x will enable the model to handle sequences of length x *
+                    original maximum pre-trained length.
+                `original_max_position_embeddings` (`int`, *optional*):

+                    computation. If unspecified, it defaults to value recommended by the implementation, using the
+                    `factor` field to infer the suggested value.
+                `beta_fast` (`float`, *optional*):
+                    Only used with 'yarn'. Parameter to set the boundary for extrapolation (only) in the linear
+                    ramp function. If unspecified, it defaults to 32.
+                `beta_slow` (`float`, *optional*):
+                    Only used with 'yarn'. Parameter to set the boundary for interpolation (only) in the linear
+                    ramp function. If unspecified, it defaults to 1.
+                `short_factor` (`List[float]`, *optional*):
+                    Only used with 'longrope'. The scaling factor to be applied to short contexts (<
+                    `original_max_position_embeddings`). Must be a list of numbers with the same length as the hidden
+                    size divided by the number of attention heads divided by 2
+                `long_factor` (`List[float]`, *optional*):
+                    Only used with 'longrope'. The scaling factor to be applied to long contexts (<
+                    `original_max_position_embeddings`). Must be a list of numbers with the same length as the hidden
+                    size divided by the number of attention heads divided by 2
+                `low_freq_factor` (`float`, *optional*):
+                    Only used with 'llama3'. Scaling factor applied to low frequency components of the RoPE
+                `high_freq_factor` (`float`, *optional*):
+                    Only used with 'llama3'. Scaling factor applied to high frequency components of the RoPE
+        use_qkv_bias (`bool`, *optional*, defaults to `False`):
+            Whether or not the model should use bias for qkv layers.
+        qk_layernorm (`bool`, *optional*, defaults to `False`):
+            Whether or not to normalize, per head, the Queries and Keys after projecting the hidden states.
+        use_parallel_residual (`bool`, *optional*, defaults to `False`):
+            Whether to use a "parallel" formulation in each Transformer layer, which can provide a slight training
+            speedup at large scales.
+        hidden_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio after applying the MLP to the hidden states.

+            - a [`~cache_utils.Cache`] instance, see our
+            [kv cache guide](https://huggingface.co/docs/transformers/en/kv_cache);
+            - Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of
+            shape `(batch_size, num_heads, sequence_length, embed_size_per_head)`). This is also known as the legacy
+            cache format.
+
+            The model will output the same cache format that is fed as input. If no `past_key_values` are passed, the
+            legacy cache format will be returned.
+
+            If `past_key_values` are used, the user can optionally input only the last `input_ids` (those that don't
+            have their past key value states given to this model) of shape `(batch_size, 1)` instead of all `input_ids`
+            of shape `(batch_size, sequence_length)`.
+        inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
+            model's internal embedding lookup matrix.
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+            `past_key_values`).
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail.
+        return_dict (`bool`, *optional*):
+            Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.
+        cache_position (`torch.LongTensor` of shape `(sequence_length)`, *optional*):
+            Indices depicting the position of the input sequence tokens in the sequence. Contrarily to `position_ids`,
+            this tensor is not affected by padding. It is used to update the cache in the correct position and to infer
+            the complete sequence length.

+                config.vocab_size]` or -100 (see `input_ids` docstring). Tokens with indices set to `-100` are ignored
+                (masked), the loss is only computed for the tokens with labels in `[0, ..., config.vocab_size]`.
+
+            logits_to_keep (`int` or `torch.Tensor`, *optional*):
+                If an `int`, compute logits for the last `logits_to_keep` tokens. If `0`, calculate logits for all
+                `input_ids` (special case). Only last token logits are needed for generation, and calculating them only for that
+                token can save memory, which becomes pretty significant for long sequences or large vocabulary size.
+                If a `torch.Tensor`, must be 1D corresponding to the indices to keep in the sequence length dimension.
+                This is useful when using packed tensor format (single dimension for batch and sequence length).

+class Starcoder2Config(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`Starcoder2Model`]. It is used to instantiate a
+    Starcoder2 model according to the specified arguments, defining the model architecture. Instantiating a configuration
+    with the defaults will yield a similar configuration to that of the [bigcode/starcoder2-7b](https://huggingface.co/bigcode/starcoder2-7b) model.
+
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 49152):
+            Vocabulary size of the Starcoder2 model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`Starcoder2Model`]
+        hidden_size (`int`, *optional*, defaults to 3072):
+            Dimension of the hidden representations.
+        intermediate_size (`int`, *optional*, defaults to 12288):
+            Dimension of the MLP representations.
+        num_hidden_layers (`int`, *optional*, defaults to 30):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 24):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        num_key_value_heads (`int`, *optional*, defaults to 2):
+            This is the number of key_value heads that should be used to implement Grouped Query Attention. If
+            `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
+            `num_key_value_heads=1` the model will use Multi Query Attention (MQA) otherwise GQA is used. When
+            converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
+            by meanpooling all the original heads within that group. For more details checkout [this
+            paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to `8`.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu_pytorch_tanh"`):
+            The non-linear activation function (function or string) in the decoder.
+        max_position_embeddings (`int`, *optional*, defaults to 4096):
+            The maximum sequence length that this model might ever be used with. Starcoder2's sliding window attention
+            allows sequence of up to 4096*32 tokens.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        norm_epsilon (`float`, *optional*, defaults to 1e-05):
+            Epsilon value for the layer norm
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should return the last key/values attentions (not used by all models). Only
+            relevant if `config.is_decoder=True`.
+        bos_token_id (`int`, *optional*, defaults to 50256):
+            The id of the "beginning-of-sequence" token.
+        eos_token_id (`int`, *optional*, defaults to 50256):
+            The id of the "end-of-sequence" token.
+        rope_theta (`float`, *optional*, defaults to 10000.0):
+            The base period of the RoPE embeddings.
+        rope_scaling (`Dict`, *optional*):
+            Dictionary containing the scaling configuration for the RoPE embeddings. NOTE: if you apply new rope type
+            and you expect the model to work on longer `max_position_embeddings`, we recommend you to update this value
+            accordingly.

+                `rope_type` (`str`):
+                    The sub-variant of RoPE to use. Can be one of ['default', 'linear', 'dynamic', 'yarn', 'longrope',
+                    'llama3'], with 'default' being the original RoPE implementation.
+                `factor` (`float`, *optional*):
+                    Used with all rope types except 'default'. The scaling factor to apply to the RoPE embeddings. In
+                    most scaling types, a `factor` of x will enable the model to handle sequences of length x *
+                    original maximum pre-trained length.
+                `original_max_position_embeddings` (`int`, *optional*):

+                `attention_factor` (`float`, *optional*):
+                    Used with 'yarn' and 'longrope'. The scaling factor to be applied on the attention
+                    computation. If unspecified, it defaults to value recommended by the implementation, using the
+                    `factor` field to infer the suggested value.
+                `beta_fast` (`float`, *optional*):
+                    Only used with 'yarn'. Parameter to set the boundary for extrapolation (only) in the linear
+                    ramp function. If unspecified, it defaults to 32.
+                `beta_slow` (`float`, *optional*):
+                    Only used with 'yarn'. Parameter to set the boundary for interpolation (only) in the linear
+                    ramp function. If unspecified, it defaults to 1.
+                `short_factor` (`List[float]`, *optional*):
+                    Only used with 'longrope'. The scaling factor to be applied to short contexts (<
+                    `original_max_position_embeddings`). Must be a list of numbers with the same length as the hidden
+                    size divided by the number of attention heads divided by 2
+                `long_factor` (`List[float]`, *optional*):
+                    Only used with 'longrope'. The scaling factor to be applied to long contexts (<
+                    `original_max_position_embeddings`). Must be a list of numbers with the same length as the hidden
+                    size divided by the number of attention heads divided by 2
+                `low_freq_factor` (`float`, *optional*):
+                    Only used with 'llama3'. Scaling factor applied to low frequency components of the RoPE
+                `high_freq_factor` (`float`, *optional*):
+                    Only used with 'llama3'. Scaling factor applied to high frequency components of the RoPE
+        sliding_window (`int`, *optional*):
+            Sliding window attention window size. If not specified, will default to `None` (no sliding window).
+        attention_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        residual_dropout (`float`, *optional*, defaults to 0.0):
+            Residual connection dropout value.
+        embedding_dropout (`float`, *optional*, defaults to 0.0):
+            Embedding dropout.

+            it.
+
+            Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.encode`] and
+            [`PreTrainedTokenizer.__call__`] for details.

+            [What are input IDs?](../glossary#input-ids)
+        attention_mask (`torch.Tensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
+
+            - 1 for tokens that are **not masked**,
+            - 0 for tokens that are **masked**.
+
+            [What are attention masks?](../glossary#attention-mask)

+
+            If `past_key_values` is used, optionally only the last `input_ids` have to be input (see
+            `past_key_values`).
+
+            If you want to change padding behavior, you should read [`modeling_opt._prepare_decoder_attention_mask`]
+            and modify to your needs. See diagram 1 in [the paper](https://arxiv.org/abs/1910.13461) for more
+            information on the default strategy.
+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
+        position_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Indices of positions of each input sequence tokens in the position embeddings. Selected in the range `[0,
+            config.n_positions - 1]`.
+
+            [What are position IDs?](../glossary#position-ids)
+        past_key_values (`Cache` or `tuple(tuple(torch.FloatTensor))`, *optional*):
+            Pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention
+            blocks) that can be used to speed up sequential decoding. This typically consists in the `past_key_values`
+            returned by the model at a previous stage of decoding, when `use_cache=True` or `config.use_cache=True`.
+
+            Two formats are allowed:
+            - a [`~cache_utils.Cache`] instance, see our
+            [kv cache guide](https://huggingface.co/docs/transformers/en/kv_cache);
+            - Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of
+            shape `(batch_size, num_heads, sequence_length, embed_size_per_head)`). This is also known as the legacy
+            cache format.
+
+            The model will output the same cache format that is fed as input. If no `past_key_values` are passed, the
+            legacy cache format will be returned.
+
+            If `past_key_values` are used, the user can optionally input only the last `input_ids` (those that don't
+            have their past key value states given to this model) of shape `(batch_size, 1)` instead of all `input_ids`
+            of shape `(batch_size, sequence_length)`.
+        inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
+            model's internal embedding lookup matrix.
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+            `past_key_values`).
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail.
+        return_dict (`bool`, *optional*):
+            Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.
+        cache_position (`torch.LongTensor` of shape `(sequence_length)`, *optional*):
+            Indices depicting the position of the input sequence tokens in the sequence. Contrarily to `position_ids`,
+            this tensor is not affected by padding. It is used to update the cache in the correct position and to infer
+            the complete sequence length.

+    This is the configuration class to store the configuration of a [`SuperGlueModel`]. It is used to instantiate a
+    SuperGlue model according to the specified arguments, defining the model architecture. Instantiating a
+    configuration with the defaults will yield a similar configuration to that of the SuperGlue
+    [magic-leap-community/superglue_indoor](https://huggingface.co/magic-leap-community/superglue_indoor) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        keypoint_detector_config (`Union[AutoConfig, dict]`,  *optional*, defaults to `SuperPointConfig`):
+            The config object or dictionary of the keypoint detector.
+        hidden_size (`int`, *optional*, defaults to 256):
+            The dimension of the descriptors.
+        keypoint_encoder_sizes (`List[int]`, *optional*, defaults to `[32, 64, 128, 256]`):
+            The sizes of the keypoint encoder layers.
+        gnn_layers_types (`List[str]`, *optional*, defaults to `['self', 'cross', 'self', 'cross', 'self', 'cross', 'self', 'cross', 'self', 'cross', 'self', 'cross', 'self', 'cross', 'self', 'cross', 'self', 'cross']`):
+            The types of the GNN layers. Must be either 'self' or 'cross'.
+        num_attention_heads (`int`, *optional*, defaults to 4):
+            The number of heads in the GNN layers.
+        sinkhorn_iterations (`int`, *optional*, defaults to 100):
+            The number of Sinkhorn iterations.
+        matching_threshold (`float`, *optional*, defaults to 0.0):
+            The matching threshold.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.

+class SuperPointConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`SuperPointForKeypointDetection`]. It is used to instantiate a
+    SuperPoint model according to the specified arguments, defining the model architecture. Instantiating a
+    configuration with the defaults will yield a similar configuration to that of the SuperPoint
+    [magic-leap-community/superpoint](https://huggingface.co/magic-leap-community/superpoint) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        encoder_hidden_sizes (`List`, *optional*, defaults to `[64, 64, 128, 128]`):
+            The number of channels in each convolutional layer in the encoder.
+        decoder_hidden_size (`int`, *optional*, defaults to 256): The hidden size of the decoder.
+        keypoint_decoder_dim (`int`, *optional*, defaults to 65): The output dimension of the keypoint decoder.
+        descriptor_decoder_dim (`int`, *optional*, defaults to 256): The output dimension of the descriptor decoder.
+        keypoint_threshold (`float`, *optional*, defaults to 0.005):
+            The threshold to use for extracting keypoints.
+        max_keypoints (`int`, *optional*, defaults to -1):
+            The maximum number of keypoints to extract. If `-1`, will extract all keypoints.
+        nms_radius (`int`, *optional*, defaults to 4):
+            The radius for non-maximum suppression.
+        border_removal_distance (`int`, *optional*, defaults to 4):
+            The distance from the border to remove keypoints.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+
+    Example:
+    ```python
+    >>> from transformers import SuperPointConfig, SuperPointForKeypointDetection
+
+    >>> # Initializing a SuperPoint superpoint style configuration
+    >>> configuration = SuperPointConfig()
+    >>> # Initializing a model from the superpoint style configuration

+    This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it
+    as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and
+    behavior.
+
+    <Tip>
+
+    TF 2.0 models accepts two formats as inputs:
+    - having all inputs as keyword arguments (like PyTorch models), or
+    - having all inputs as a list, tuple or dict in the first positional arguments.
+    This second option is useful when using [`keras.Model.fit`] method which currently requires having all the
+    tensors in the first argument of the model call function: `model(inputs)`.
+    If you choose this second option, there are three possibilities you can use to gather all the input Tensors in the
+    first positional argument :
+    - a single Tensor with `input_ids` only and nothing else: `model(input_ids)`
+    - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
+      `model([input_ids, attention_mask])` or `model([input_ids, attention_mask, token_type_ids])`
+    - a dictionary with one or several input Tensors associated to the input names given in the docstring:
+      `model({"input_ids": input_ids, "token_type_ids": token_type_ids})`
+
+    </Tip>
+
+    Parameters:
+        config ([`SwiftFormerConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+    r"""
+    This is the configuration class to store the configuration of a [`SwinModel`]. It is used to instantiate a Swin
+    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
+    defaults will yield a similar configuration to that of the Swin
+    [microsoft/swin-tiny-patch4-window7-224](https://huggingface.co/microsoft/swin-tiny-patch4-window7-224)
+    architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        image_size (`int`, *optional*, defaults to 224):
+            The size (resolution) of each image.
+        patch_size (`int`, *optional*, defaults to 4):
+            The size (resolution) of each patch.
+        num_channels (`int`, *optional*, defaults to 3):
+            The number of input channels.
+        embed_dim (`int`, *optional*, defaults to 96):
+            Dimensionality of patch embedding.
+        depths (`list(int)`, *optional*, defaults to `[2, 2, 6, 2]`):
+            Depth of each layer in the Transformer encoder.
+        num_heads (`list(int)`, *optional*, defaults to `[3, 6, 12, 24]`):
+            Number of attention heads in each layer of the Transformer encoder.
+        window_size (`int`, *optional*, defaults to 7):
+            Size of windows.
+        mlp_ratio (`float`, *optional*, defaults to 4.0):
+            Ratio of MLP hidden dimensionality to embedding dimensionality.
+        qkv_bias (`bool`, *optional*, defaults to `True`):
+            Whether or not a learnable bias should be added to the queries, keys and values.
+        hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout probability for all fully connected layers in the embeddings and encoder.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        drop_path_rate (`float`, *optional*, defaults to 0.1):
+            Stochastic depth rate.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder. If string, `"gelu"`, `"relu"`,
+            `"selu"` and `"gelu_new"` are supported.
+        use_absolute_embeddings (`bool`, *optional*, defaults to `False`):
+            Whether or not to add absolute position embeddings to the patch embeddings.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-05):
+            The epsilon used by the layer normalization layers.
+        encoder_stride (`int`, *optional*, defaults to 32):
+            Factor to increase the spatial resolution by in the decoder head for masked image modeling.
+        out_features (`List[str]`, *optional*):
+            If used as backbone, list of features to output. Can be any of `"stem"`, `"stage1"`, `"stage2"`, etc.
+            (depending on how many stages the model has). If unset and `out_indices` is set, will default to the
+            corresponding stages. If unset and `out_indices` is unset, will default to the last stage. Must be in the
+            same order as defined in the `stage_names` attribute.
+        out_indices (`List[int]`, *optional*):
+            If used as backbone, list of indices of features to output. Can be any of 0, 1, 2, etc. (depending on how
+            many stages the model has). If unset and `out_features` is set, will default to the corresponding stages.
+            If unset and `out_features` is unset, will default to the last stage. Must be in the
+            same order as defined in the `stage_names` attribute.
+
+    Example:
+
+    ```python
+    >>> from transformers import SwinConfig, SwinModel

+    This is the configuration class to store the configuration of a [`Swinv2Model`]. It is used to instantiate a Swin
+    Transformer v2 model according to the specified arguments, defining the model architecture. Instantiating a
+    configuration with the defaults will yield a similar configuration to that of the Swin Transformer v2
+    [microsoft/swinv2-tiny-patch4-window8-256](https://huggingface.co/microsoft/swinv2-tiny-patch4-window8-256)
+    architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        image_size (`int`, *optional*, defaults to 224):
+            The size (resolution) of each image.
+        patch_size (`int`, *optional*, defaults to 4):
+            The size (resolution) of each patch.
+        num_channels (`int`, *optional*, defaults to 3):
+            The number of input channels.
+        embed_dim (`int`, *optional*, defaults to 96):

+            Number of attention heads in each layer of the Transformer encoder.
+        window_size (`int`, *optional*, defaults to 7):
+            Size of windows.
+        pretrained_window_sizes (`list(int)`, *optional*, defaults to `[0, 0, 0, 0]`):
+            Size of windows during pretraining.
+        mlp_ratio (`float`, *optional*, defaults to 4.0):
+            Ratio of MLP hidden dimensionality to embedding dimensionality.
+        qkv_bias (`bool`, *optional*, defaults to `True`):
+            Whether or not a learnable bias should be added to the queries, keys and values.
+        hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout probability for all fully connected layers in the embeddings and encoder.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        drop_path_rate (`float`, *optional*, defaults to 0.1):
+            Stochastic depth rate.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder. If string, `"gelu"`, `"relu"`,
+            `"selu"` and `"gelu_new"` are supported.
+        use_absolute_embeddings (`bool`, *optional*, defaults to `False`):
+            Whether or not to add absolute position embeddings to the patch embeddings.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-05):
+            The epsilon used by the layer normalization layers.
+        encoder_stride (`int`, *optional*, defaults to 32):
+            Factor to increase the spatial resolution by in the decoder head for masked image modeling.
+        out_features (`List[str]`, *optional*):
+            If used as backbone, list of features to output. Can be any of `"stem"`, `"stage1"`, `"stage2"`, etc.
+            (depending on how many stages the model has). If unset and `out_indices` is set, will default to the
+            corresponding stages. If unset and `out_indices` is unset, will default to the last stage.
+        out_indices (`List[int]`, *optional*):
+            If used as backbone, list of indices of features to output. Can be any of 0, 1, 2, etc. (depending on how
+            many stages the model has). If unset and `out_features` is set, will default to the corresponding stages.
+            If unset and `out_features` is unset, will default to the last stage.

+
+
+class SwitchTransformersConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`SwitchTransformersModel`]. It is used to
+    instantiate a SwitchTransformers model according to the specified arguments, defining the model architecture.
+    Instantiating a configuration with the defaults will yield a similar configuration to that of the
+    SwitchTransformers [google/switch-base-8](https://huggingface.co/google/switch-base-8) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Arguments:
+        vocab_size (`int`, *optional*, defaults to 32128):
+            Vocabulary size of the SwitchTransformers model. Defines the number of different tokens that can be
+            represented by the `inputs_ids` passed when calling [`SwitchTransformersModel`].
+        d_model (`int`, *optional*, defaults to 768):
+            Size of the encoder layers and the pooler layer.
+        d_kv (`int`, *optional*, defaults to 64):
+            Size of the key, query, value projections per attention head. `d_kv` has to be equal to `d_model //
+            num_heads`.
+        d_ff (`int`, *optional*, defaults to 2048):
+            Size of the intermediate feed forward layer in each `SwitchTransformersBlock`.
+        expert_capacity (`int`, *optional*, defaults to 64):
+            Number of tokens that can be stored in each expert. If set to 1, the model will behave like a regular
+            Transformer.
+        num_layers (`int`, *optional*, defaults to 12):
+            Number of dense hidden layers in the Transformer encoder layer.
+        num_sparse_encoder_layers (`int`, *optional*, defaults to 3):
+            Number of sparse (MoE) dense hidden layers in the Transformer encoder layer.
+        num_decoder_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer decoder. Will use the same value as `num_layers` if not set.
+        num_sparse_decoder_layers (`int`, *optional*, defaults to 3):
+            Number of sparse (MoE) dense hidden layers in the Transformer decoder layer.
+        num_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        num_experts (`int`, *optional*, defaults to 8):
+            Number of experts for each SwitchTransformer layer.
+        router_bias (`bool`, *optional*, defaults to `False`):
+            Whether to add a bias to the router.
+        router_jitter_noise (`float`, *optional*, defaults to 0.01):
+            Amount of noise to add to the router.
+        router_dtype (`str`, *optional*, default to `"float32"`):
+            The `dtype` used for the routers. It is preferable to keep the `dtype` to `"float32"` as specified in the
+            *selective precision* discussion in [the paper](https://arxiv.org/abs/2101.03961).
+        router_ignore_padding_tokens (`bool`, *optional*, defaults to `False`):
+            Whether to ignore padding tokens when routing.
+        relative_attention_num_buckets (`int`, *optional*, defaults to 32):
+            The number of buckets to use for each attention layer.
+        relative_attention_max_distance (`int`, *optional*, defaults to 128):
+            The maximum distance of the longer sequences for the bucket separation.
+        dropout_rate (`float`, *optional*, defaults to 0.1):
+            The ratio for all dropout layers.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-6):
+            The epsilon used by the layer normalization layers.
+        router_z_loss_coef (`float`, *optional*, defaults to 0.001):
+            The z loss factor for the total loss.
+        router_aux_loss_coef (`float`, *optional*, defaults to 0.001):
+            The aux loss factor for the total loss.
+        initializer_factor (`float`, *optional*, defaults to 1.0):
+            A factor for initializing all weight matrices (should be kept to 1, used internally for initialization
+            testing).
+        dense_act_fn (`string`, *optional*, defaults to `"relu"`):
+            Type of feed forward layer to be used. Should be one of `"relu"` or `"gated-gelu"`. SwitchTransformersv1.1
+            uses the `"gated-gelu"` feed forward projection. Original SwitchTransformers uses `"relu"`.
+        add_router_probs (`bool`, *optional*, defaults to `False`):
+            Whether to output router probabilities to compute router auxiliary loss.
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should return the last key/values attentions (not used by all models).

+    Shazeer](https://arxiv.org/search/cs?searchtype=author&query=Shazeer%2C+N). It's an encoder-decoder T5-like model
+    with sparse Feed Forward that stands for Mixture of Experts (MoE) architecture.
+
+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass.
+    Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
+    and behavior.
+
+    Parameters:
+        config ([`SwitchTransformersConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+            [What are decoder input IDs?](../glossary#decoder-input-ids)
+
+            SWITCH_TRANSFORMERS uses the `pad_token_id` as the starting token for `decoder_input_ids` generation. If
+            `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
+            `past_key_values`).
+
+            To know more on how to prepare `decoder_input_ids` for pretraining take a look at [SWITCH_TRANSFORMERS
+            Training](./switch_transformers#training).
+        decoder_attention_mask (`torch.BoolTensor` of shape `(batch_size, target_sequence_length)`, *optional*):
+            Default behavior: generate a tensor that ignores pad tokens in `decoder_input_ids`. Causal mask will also
+            be used by default.
+        head_mask (`torch.FloatTensor` of shape `(num_heads,)` or `(num_layers, num_heads)`, *optional*):
+            Mask to nullify selected heads of the self-attention modules in the encoder. Mask values selected in `[0,
+            1]`:
+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
+
+        decoder_head_mask (`torch.FloatTensor` of shape `(num_heads,)` or `(num_layers, num_heads)`, *optional*):
+            Mask to nullify selected heads of the self-attention modules in the decoder. Mask values selected in `[0,
+            1]`:
+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
+
+        cross_attn_head_mask (`torch.Tensor` of shape `(num_heads,)` or `(num_layers, num_heads)`, *optional*):
+                Mask to nullify selected heads of the cross-attention modules in the decoder. Mask values selected in
+                `[0, 1]`:
+
+                - 1 indicates the head is **not masked**,
+                - 0 indicates the head is **masked**.
+
+        encoder_outputs (`tuple(tuple(torch.FloatTensor)`, *optional*):
+            Tuple consists of (`last_hidden_state`, `optional`: *hidden_states*, `optional`: *attentions*)
+            `last_hidden_state` of shape `(batch_size, sequence_length, hidden_size)` is a sequence of hidden states at
+            the output of the last layer of the encoder. Used in the cross-attention of the decoder.
+        past_key_values (`tuple(tuple(torch.FloatTensor))` of length `config.n_layers` with each tuple having 4 tensors of shape `(batch_size, num_heads, sequence_length - 1, embed_size_per_head)`):
+            Contains precomputed key and value hidden states of the attention blocks. Can be used to speed up decoding.
+
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
+            don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all
+            `decoder_input_ids` of shape `(batch_size, sequence_length)`.
+        inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
+            model's internal embedding lookup matrix.
+        decoder_inputs_embeds (`torch.FloatTensor` of shape `(batch_size, target_sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `decoder_input_ids` you can choose to directly pass an embedded
+            representation. If `past_key_values` is used, optionally only the last `decoder_inputs_embeds` have to be
+            input (see `past_key_values`). This is useful if you want more control over how to convert
+            `decoder_input_ids` indices into associated vectors than the model's internal embedding lookup matrix.
+
+            If `decoder_input_ids` and `decoder_inputs_embeds` are both unset, `decoder_inputs_embeds` takes the value
+            of `inputs_embeds`.
+
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+            `past_key_values`).
+
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail.
+        output_router_logits (`bool`, *optional*):
+            Whether or not to return the logits of all the routers. They are useful for computing the router loss, and
+            should not be returned during inference.
+        return_dict (`bool`, *optional*):
+            Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.
+        cache_position (`torch.LongTensor` of shape `(sequence_length)`, *optional*):
+            Indices depicting the position of the input sequence tokens in the sequence. It is used to update the
+            cache in the correct position and to infer the complete sequence length.

+    This is the configuration class to store the configuration of a [`T5Model`] or a [`TFT5Model`]. It is used to

+    Arguments:
+        vocab_size (`int`, *optional*, defaults to 32128):
+            Vocabulary size of the T5 model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`T5Model`] or [`TFT5Model`].
+        d_model (`int`, *optional*, defaults to 512):
+            Size of the encoder layers and the pooler layer.
+        d_kv (`int`, *optional*, defaults to 64):
+            Size of the key, query, value projections per attention head. The `inner_dim` of the projection layer will
+            be defined as `num_heads * d_kv`.
+        d_ff (`int`, *optional*, defaults to 2048):
+            Size of the intermediate feed forward layer in each `T5Block`.
+        num_layers (`int`, *optional*, defaults to 6):

+Convert T5X checkpoint to PyTorch
+
+Steps:
+- Install gsutil according to https://cloud.google.com/storage/docs/gsutil_install
+- Get a T5X checkpoint at https://github.com/google-research/t5x/blob/main/docs/models.md#t5-11-checkpoints Example:
+    `gsutil -m cp -r gs://t5-data/pretrained_models/t5x/t5_1_1_small $HOME/`
+- Create or download a corresponding config for the downloaded model. E.g. for T5 v1.1 small, you can use
+    https://huggingface.co/google/t5-v1_1-small/blob/main/config.json
+- Convert:
+    ```
+    python3 convert_t5x_checkpoint_to_pytorch.py --t5x_checkpoint_path=$HOME/t5_1_1_small --config_file=config.json\
+      --pytorch_dump_path=$HOME/t5_1_1_small_pt

+    The T5 model was proposed in [Exploring the Limits of Transfer Learning with a Unified Text-to-Text
+    Transformer](https://arxiv.org/abs/1910.10683) by Colin Raffel, Noam Shazeer, Adam Roberts, Katherine Lee, Sharan
+    Narang, Michael Matena, Yanqi Zhou, Wei Li, Peter J. Liu. It's an encoder decoder transformer pre-trained in a
+    text-to-text denoising generative setting.
+
+    This model inherits from [`FlaxPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a Flax Linen
+    [flax.nn.Module](https://flax.readthedocs.io/en/latest/_autosummary/flax.nn.module.html) subclass. Use it as a
+    regular Flax Module and refer to the Flax documentation for all matter related to general usage and behavior.
+
+    Finally, this model supports inherent JAX features such as:
+
+    - [Just-In-Time (JIT) compilation](https://jax.readthedocs.io/en/latest/jax.html#just-in-time-compilation-jit)
+    - [Automatic Differentiation](https://jax.readthedocs.io/en/latest/jax.html#automatic-differentiation)
+    - [Vectorization](https://jax.readthedocs.io/en/latest/jax.html#vectorization-vmap)
+    - [Parallelization](https://jax.readthedocs.io/en/latest/jax.html#parallelization-pmap)
+
+    Parameters:
+        config ([`T5Config`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~FlaxPreTrainedModel.from_pretrained`] method to load the model weights.
+        dtype (`jax.numpy.dtype`, *optional*, defaults to `jax.numpy.float32`):
+            The data type of the computation. Can be one of `jax.numpy.float32`, `jax.numpy.float16` (on GPUs) and
+            `jax.numpy.bfloat16` (on TPUs).
+
+            This can be used to enable mixed-precision training or half-precision inference on GPUs or TPUs. If
+            specified all the computation will be performed with the given `dtype`.
+
+            **Note that this only specifies the dtype of the computation and does not influence the dtype of model
+            parameters.**
+
+            If you wish to change the dtype of the model parameters, see [`~FlaxPreTrainedModel.to_fp16`] and
+            [`~FlaxPreTrainedModel.to_bf16`].

+    Narang, Michael Matena, Yanqi Zhou, Wei Li, Peter J. Liu. It's an encoder decoder transformer pre-trained in a
+    text-to-text denoising generative setting.
+
+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass.
+    Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
+    and behavior.
+
+    Parameters:
+        config ([`T5Config`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the

+
+    The T5 model was proposed in [Exploring the Limits of Transfer Learning with a Unified Text-to-Text
+    Transformer](https://arxiv.org/abs/1910.10683) by Colin Raffel, Noam Shazeer, Adam Roberts, Katherine Lee, Sharan
+    Narang, Michael Matena, Yanqi Zhou, Wei Li, Peter J. Liu. It's an encoder decoder transformer pre-trained in a
+    text-to-text denoising generative setting.
+
+    This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it
+    as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and
+    behavior.
+
+    <Tip>
+
+    TensorFlow models and layers in `transformers` accept two formats as input:
+
+    - having all inputs as keyword arguments (like PyTorch models), or
+    - having all inputs as a list, tuple or dict in the first positional argument.
+
+    The reason the second format is supported is that Keras methods prefer this format when passing inputs to models
+    and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just
+    pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second
+    format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with
+    the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first
+    positional argument:
+
+    - a single Tensor with `input_ids` only and nothing else: `model(input_ids)`
+    - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
+    `model([input_ids, attention_mask])` or `model([input_ids, attention_mask, token_type_ids])`
+    - a dictionary with one or several input Tensors associated to the input names given in the docstring:
+    `model({"input_ids": input_ids, "token_type_ids": token_type_ids})`
+
+    Note that when creating models and layers with
+    [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry
+    about any of this, as you can just pass inputs like you would to any other Python function!
+
+    </Tip>
+
+    Parameters:
+        config ([`T5Config`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+            be used by default.
+        head_mask (`tf.Tensor` of shape `(num_heads,)` or `(num_layers, num_heads)`, *optional*):
+            Mask to nullify selected heads of the self-attention modules in the encoder. Mask values selected in `[0,
+            1]`:
+
+            - 1 indicates the head is **not masked**,

+            contains precomputed key and value hidden states of the attention blocks. Can be used to speed up decoding.
+
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
+            don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all

+

+class T5Tokenizer(PreTrainedTokenizer):
+    """
+    Construct a T5 tokenizer. Based on [SentencePiece](https://github.com/google/sentencepiece).
+
+    This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to
+    this superclass for more information regarding those methods.
+
+    Args:
+        vocab_file (`str`):
+            [SentencePiece](https://github.com/google/sentencepiece) file (generally has a *.spm* extension) that
+            contains the vocabulary necessary to instantiate a tokenizer.
+        eos_token (`str`, *optional*, defaults to `"</s>"`):
+            The end of sequence token.
+
+            <Tip>
+
+            When building a sequence using special tokens, this is not the token that is used for the end of sequence.
+            The token used is the `sep_token`.
+
+            </Tip>
+
+        unk_token (`str`, *optional*, defaults to `"<unk>"`):
+            The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
+            token instead.
+        pad_token (`str`, *optional*, defaults to `"<pad>"`):
+            The token used for padding, for example when batching sequences of different lengths.
+        extra_ids (`int`, *optional*, defaults to 100):
+           Add a number of extra ids added to the vocabulary for use as sentinels. These tokens are
+            accessible as "<extra_id_{%d}>" where "{%d}" is a number between 0 and extra_ids-1. These tokens can be
+            retrieved by calling get_sentinel_tokens method and token ids can be by calling get_sentinel_token_ids
+            method
+         additional_special_tokens (`List[str]`, *optional*):
+            Additional special tokens used by the tokenizer.
+        sp_model_kwargs (`dict`, *optional*):
+            Will be passed to the `SentencePieceProcessor.__init__()` method. The [Python wrapper for
+            SentencePiece](https://github.com/google/sentencepiece/tree/master/python) can be used, among other things,
+            to set:
+
+            - `enable_sampling`: Enable subword regularization.
+            - `nbest_size`: Sampling parameters for unigram. Invalid for BPE-Dropout.
+
+              - `nbest_size = {0,1}`: No sampling is performed.
+              - `nbest_size > 1`: samples from the nbest_size results.
+              - `nbest_size < 0`: assuming that nbest_size is infinite and samples from the all hypothesis (lattice)
+                using forward-filtering-and-backward-sampling algorithm.
+
+            - `alpha`: Smoothing parameter for unigram sampling, and dropout probability of merge operations for
+              BPE-dropout.
+        legacy (`bool`, *optional*):
+            Whether or not the `legacy` behaviour of the tokenizer should be used. Legacy is before the merge of #24622
+            and #25224 which includes fixes to properly handle tokens that appear after special tokens. A simple
+            example:
+
+            - `legacy=True`:
+            ```python
+            >>> from transformers import T5Tokenizer
+
+            >>> tokenizer = T5Tokenizer.from_pretrained("google-t5/t5-base", legacy=True)
+            >>> tokenizer.encode("Hello <extra_id_0>.")
+            [8774, 32099, 3, 5, 1]
+            ```
+            - `legacy=False`:
+            ```python
+            >>> from transformers import T5Tokenizer
+
+            >>> tokenizer = T5Tokenizer.from_pretrained("google-t5/t5-base", legacy=False)
+            >>> tokenizer.encode("Hello <extra_id_0>.")  # the extra space `[3]` is no longer here
+            [8774, 32099, 5, 1]
+            ```
+            Checkout the [pull request](https://github.com/huggingface/transformers/pull/24565) for more details.
+        add_prefix_space (`bool`, *optional*, defaults to `False`):
+            Whether or not to add an initial space to the input. This allows to treat the leading word just as any
+            other word.
+
+    Attributes:
+        sp_model (`SentencePieceProcessor`):
+            The *SentencePiece* processor that is used for every conversion (string, tokens and IDs).

+    This is the configuration class to store the configuration of a [`TapasModel`]. It is used to instantiate a TAPAS
+    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
+    defaults will yield a similar configuration to that of the TAPAS
+    [google/tapas-base-finetuned-sqa](https://huggingface.co/google/tapas-base-finetuned-sqa) architecture.
+
+    Configuration objects inherit from [`PreTrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Hyperparameters additional to BERT are taken from run_task_main.py and hparam_utils.py of the original
+    implementation. Original implementation available at https://github.com/google-research/tapas/tree/master.

+        cell_selection_preference (`float`, *optional*):
+            Preference for cell selection in ambiguous cases. Only applicable in case of weak supervision for
+            aggregation (WTQ, WikiSQL). If the total mass of the aggregation probabilities (excluding the "NONE"

+        init_cell_selection_weights_to_zero (`bool`, *optional*, defaults to `False`):
+            Whether to initialize cell selection weights to 0 so that the initial probabilities are 50%.
+        reset_position_index_per_cell (`bool`, *optional*, defaults to `True`):
+            Whether to restart position indexes at every cell (i.e. use relative position embeddings).
+        disable_per_token_loss (`bool`, *optional*, defaults to `False`):
+            Whether to disable any (strong or weak) supervision on cells.
+        aggregation_labels (`Dict[int, label]`, *optional*):
+            The aggregation labels used to aggregate the results. For example, the WTQ models have the following
+            aggregation labels: `{0: "NONE", 1: "SUM", 2: "AVERAGE", 3: "COUNT"}`
+        no_aggregation_label_index (`int`, *optional*):
+            If the aggregation labels are defined and one of these labels represents "No aggregation", this should be
+            set to its index. For example, the WTQ models have the "NONE" aggregation label at index 0, so that value
+            should be set to 0 for these models.

+    This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the

+    etc.)
+
+    This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it
+    as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and
+    behavior.
+
+    <Tip>
+
+    TensorFlow models and layers in `transformers` accept two formats as input:
+
+    - having all inputs as keyword arguments (like PyTorch models), or
+    - having all inputs as a list, tuple or dict in the first positional argument.
+
+    The reason the second format is supported is that Keras methods prefer this format when passing inputs to models
+    and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just
+    pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second
+    format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with
+    the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first
+    positional argument:
+
+    - a single Tensor with `input_ids` only and nothing else: `model(input_ids)`
+    - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
+    `model([input_ids, attention_mask])` or `model([input_ids, attention_mask, token_type_ids])`
+    - a dictionary with one or several input Tensors associated to the input names given in the docstring:
+    `model({"input_ids": input_ids, "token_type_ids": token_type_ids})`
+
+    Note that when creating models and layers with
+    [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry
+    about any of this, as you can just pass inputs like you would to any other Python function!
+
+    </Tip>
+
+    Parameters:
+        config ([`TapasConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+class TapasTokenizer(PreTrainedTokenizer):
+    r"""
+    Construct a TAPAS tokenizer. Based on WordPiece. Flattens a table and one or more related sentences to be used by
+    TAPAS models.
+
+    This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to
+    this superclass for more information regarding those methods. [`TapasTokenizer`] creates several token type ids to
+    encode tabular structure. To be more precise, it adds 7 token type ids, in the following order: `segment_ids`,
+    `column_ids`, `row_ids`, `prev_labels`, `column_ranks`, `inv_column_ranks` and `numeric_relations`:
+
+    - segment_ids: indicate whether a token belongs to the question (0) or the table (1). 0 for special tokens and
+      padding.
+    - column_ids: indicate to which column of the table a token belongs (starting from 1). Is 0 for all question
+      tokens, special tokens and padding.
+    - row_ids: indicate to which row of the table a token belongs (starting from 1). Is 0 for all question tokens,
+      special tokens and padding. Tokens of column headers are also 0.
+    - prev_labels: indicate whether a token was (part of) an answer to the previous question (1) or not (0). Useful in
+      a conversational setup (such as SQA).
+    - column_ranks: indicate the rank of a table token relative to a column, if applicable. For example, if you have a
+      column "number of movies" with values 87, 53 and 69, then the column ranks of these tokens are 3, 1 and 2
+      respectively. 0 for all question tokens, special tokens and padding.
+    - inv_column_ranks: indicate the inverse rank of a table token relative to a column, if applicable. For example, if
+      you have a column "number of movies" with values 87, 53 and 69, then the inverse column ranks of these tokens are
+      1, 3 and 2 respectively. 0 for all question tokens, special tokens and padding.
+    - numeric_relations: indicate numeric relations between the question and the tokens of the table. 0 for all
+      question tokens, special tokens and padding.
+
+    [`TapasTokenizer`] runs end-to-end tokenization on a table and associated sentences: punctuation splitting and
+    wordpiece.
+
+    Args:
+        vocab_file (`str`):
+            File containing the vocabulary.

+            Whether or not to lowercase the input when tokenizing.
+        do_basic_tokenize (`bool`, *optional*, defaults to `True`):
+            Whether or not to do basic tokenization before WordPiece.
+        never_split (`Iterable`, *optional*):
+            Collection of tokens which will never be split during tokenization. Only has an effect when
+            `do_basic_tokenize=True`
+        unk_token (`str`, *optional*, defaults to `"[UNK]"`):
+            The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
+            token instead.
+        sep_token (`str`, *optional*, defaults to `"[SEP]"`):
+            The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for
+            sequence classification or for a text and a question for question answering. It is also used as the last
+            token of a sequence built with special tokens.
+        pad_token (`str`, *optional*, defaults to `"[PAD]"`):
+            The token used for padding, for example when batching sequences of different lengths.
+        cls_token (`str`, *optional*, defaults to `"[CLS]"`):
+            The classifier token which is used when doing sequence classification (classification of the whole sequence
+            instead of per-token classification). It is the first token of the sequence when built with special tokens.
+        mask_token (`str`, *optional*, defaults to `"[MASK]"`):
+            The token used for masking values. This is the token used when training this model with masked language
+            modeling. This is the token which the model will try to predict.
+        empty_token (`str`, *optional*, defaults to `"[EMPTY]"`):
+            The token used for empty cell values in a table. Empty cell values include "", "n/a", "nan" and "?".
+        tokenize_chinese_chars (`bool`, *optional*, defaults to `True`):
+            Whether or not to tokenize Chinese characters. This should likely be deactivated for Japanese (see this
+            [issue](https://github.com/huggingface/transformers/issues/328)).
+        strip_accents (`bool`, *optional*):
+            Whether or not to strip all accents. If this option is not specified, then it will be determined by the
+            value for `lowercase` (as in the original BERT).
+        cell_trim_length (`int`, *optional*, defaults to -1):
+            If > 0: Trim cells so that the length is <= this value. Also disables further cell trimming, should thus be

+        strip_column_names (`bool`, *optional*, defaults to `False`):
+            Whether to add empty strings instead of column names.
+        update_answer_coordinates (`bool`, *optional*, defaults to `False`):
+            Whether to recompute the answer coordinates from the answer text.
+        min_question_length (`int`, *optional*):
+            Minimum length of each question in terms of tokens (will be skipped otherwise).
+        max_question_length (`int`, *optional*):
+            Maximum length of each question in terms of tokens (will be skipped otherwise).
+        clean_up_tokenization_spaces (`bool`, *optional*, defaults to `True`):
+            Whether or not to cleanup spaces after decoding, cleanup consists in removing potential artifacts like
+            extra spaces.

+class TimeSeriesTransformerConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`TimeSeriesTransformerModel`]. It is used to
+    instantiate a Time Series Transformer model according to the specified arguments, defining the model architecture.
+    Instantiating a configuration with the defaults will yield a similar configuration to that of the Time Series
+    Transformer
+    [huggingface/time-series-transformer-tourism-monthly](https://huggingface.co/huggingface/time-series-transformer-tourism-monthly)
+    architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        prediction_length (`int`):
+            The prediction length for the decoder. In other words, the prediction horizon of the model. This value is
+            typically dictated by the dataset and we recommend to set it appropriately.
+        context_length (`int`, *optional*, defaults to `prediction_length`):
+            The context length for the encoder. If `None`, the context length will be the same as the
+            `prediction_length`.
+        distribution_output (`string`, *optional*, defaults to `"student_t"`):
+            The distribution emission head for the model. Could be either "student_t", "normal" or "negative_binomial".
+        loss (`string`, *optional*, defaults to `"nll"`):
+            The loss function for the model corresponding to the `distribution_output` head. For parametric
+            distributions it is the negative log likelihood (nll) - which currently is the only supported one.
+        input_size (`int`, *optional*, defaults to 1):
+            The size of the target variable which by default is 1 for univariate targets. Would be > 1 in case of
+            multivariate targets.
+        scaling (`string` or `bool`, *optional* defaults to `"mean"`):
+            Whether to scale the input targets via "mean" scaler, "std" scaler or no scaler if `None`. If `True`, the
+            scaler is set to "mean".
+        lags_sequence (`list[int]`, *optional*, defaults to `[1, 2, 3, 4, 5, 6, 7]`):
+            The lags of the input time series as covariates often dictated by the frequency of the data. Default is
+            `[1, 2, 3, 4, 5, 6, 7]` but we recommend to change it based on the dataset appropriately.
+        num_time_features (`int`, *optional*, defaults to 0):
+            The number of time features in the input time series.
+        num_dynamic_real_features (`int`, *optional*, defaults to 0):
+            The number of dynamic real valued features.
+        num_static_categorical_features (`int`, *optional*, defaults to 0):
+            The number of static categorical features.
+        num_static_real_features (`int`, *optional*, defaults to 0):
+            The number of static real valued features.
+        cardinality (`list[int]`, *optional*):
+            The cardinality (number of different values) for each of the static categorical features. Should be a list
+            of integers, having the same length as `num_static_categorical_features`. Cannot be `None` if
+            `num_static_categorical_features` is > 0.
+        embedding_dimension (`list[int]`, *optional*):
+            The dimension of the embedding for each of the static categorical features. Should be a list of integers,
+            having the same length as `num_static_categorical_features`. Cannot be `None` if
+            `num_static_categorical_features` is > 0.
+        d_model (`int`, *optional*, defaults to 64):
+            Dimensionality of the transformer layers.
+        encoder_layers (`int`, *optional*, defaults to 2):
+            Number of encoder layers.
+        decoder_layers (`int`, *optional*, defaults to 2):
+            Number of decoder layers.
+        encoder_attention_heads (`int`, *optional*, defaults to 2):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        decoder_attention_heads (`int`, *optional*, defaults to 2):
+            Number of attention heads for each attention layer in the Transformer decoder.
+        encoder_ffn_dim (`int`, *optional*, defaults to 32):
+            Dimension of the "intermediate" (often named feed-forward) layer in encoder.
+        decoder_ffn_dim (`int`, *optional*, defaults to 32):
+            Dimension of the "intermediate" (often named feed-forward) layer in decoder.
+        activation_function (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and decoder. If string, `"gelu"` and
+            `"relu"` are supported.
+        dropout (`float`, *optional*, defaults to 0.1):
+            The dropout probability for all fully connected layers in the encoder, and decoder.
+        encoder_layerdrop (`float`, *optional*, defaults to 0.1):
+            The dropout probability for the attention and fully connected layers for each encoder layer.
+        decoder_layerdrop (`float`, *optional*, defaults to 0.1):
+            The dropout probability for the attention and fully connected layers for each decoder layer.
+        attention_dropout (`float`, *optional*, defaults to 0.1):
+            The dropout probability for the attention probabilities.
+        activation_dropout (`float`, *optional*, defaults to 0.1):
+            The dropout probability used between the two layers of the feed-forward networks.
+        num_parallel_samples (`int`, *optional*, defaults to 100):
+            The number of samples to generate in parallel for each time step of inference.
+        init_std (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated normal weight initialization distribution.
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether to use the past key/values attentions (if applicable to the model) to speed up decoding.
+
+        Example:

+    Args:
+        past_values (`torch.FloatTensor` of shape `(batch_size, sequence_length)` or `(batch_size, sequence_length, input_size)`):
+            Past values of the time series, that serve as context in order to predict the future. The sequence size of
+            this tensor must be larger than the `context_length` of the model, since the model will use the larger size
+            to construct lag features, i.e. additional values from the past which are added in order to serve as "extra
+            context".
+
+            The `sequence_length` here is equal to `config.context_length` + `max(config.lags_sequence)`, which if no
+            `lags_sequence` is configured, is equal to `config.context_length` + 7 (as by default, the largest
+            look-back index in `config.lags_sequence` is 7). The property `_past_length` returns the actual length of
+            the past.
+
+            The `past_values` is what the Transformer encoder gets as input (with optional additional features, such as
+            `static_categorical_features`, `static_real_features`, `past_time_features` and lags).
+
+            Optionally, missing values need to be replaced with zeros and indicated via the `past_observed_mask`.
+
+            For multivariate time series, the `input_size` > 1 dimension is required and corresponds to the number of
+            variates in the time series per time step.
+        past_time_features (`torch.FloatTensor` of shape `(batch_size, sequence_length, num_features)`):
+            Required time features, which the model internally will add to `past_values`. These could be things like
+            "month of year", "day of the month", etc. encoded as vectors (for instance as Fourier features). These
+            could also be so-called "age" features, which basically help the model know "at which point in life" a
+            time-series is. Age features have small values for distant past time steps and increase monotonically the
+            more we approach the current time step. Holiday features are also a good example of time features.
+
+            These features serve as the "positional encodings" of the inputs. So contrary to a model like BERT, where
+            the position encodings are learned from scratch internally as parameters of the model, the Time Series
+            Transformer requires to provide additional time features. The Time Series Transformer only learns
+            additional embeddings for `static_categorical_features`.
+
+            Additional dynamic real covariates can be concatenated to this tensor, with the caveat that these features
+            must but known at prediction time.
+
+            The `num_features` here is equal to `config.`num_time_features` + `config.num_dynamic_real_features`.
+        past_observed_mask (`torch.BoolTensor` of shape `(batch_size, sequence_length)` or `(batch_size, sequence_length, input_size)`, *optional*):

+
+            - 1 for values that are **observed**,
+            - 0 for values that are **missing** (i.e. NaNs that were replaced by zeros).
+
+        static_categorical_features (`torch.LongTensor` of shape `(batch_size, number of static categorical features)`, *optional*):
+            Optional static categorical features for which the model will learn an embedding, which it will add to the
+            values of the time series.
+
+            Static categorical features are features which have the same value for all time steps (static over time).
+
+            A typical example of a static categorical feature is a time series ID.
+        static_real_features (`torch.FloatTensor` of shape `(batch_size, number of static real features)`, *optional*):
+            Optional static real features which the model will add to the values of the time series.
+
+            Static real features are features which have the same value for all time steps (static over time).
+
+            A typical example of a static real feature is promotion information.
+        future_values (`torch.FloatTensor` of shape `(batch_size, prediction_length)` or `(batch_size, prediction_length, input_size)`, *optional*):
+            Future values of the time series, that serve as labels for the model. The `future_values` is what the
+            Transformer needs during training to learn to output, given the `past_values`.
+
+            The sequence length here is equal to `prediction_length`.
+
+            See the demo notebook and code snippets for details.
+
+            Optionally, during training any missing values need to be replaced with zeros and indicated via the
+            `future_observed_mask`.
+
+            For multivariate time series, the `input_size` > 1 dimension is required and corresponds to the number of
+            variates in the time series per time step.
+        future_time_features (`torch.FloatTensor` of shape `(batch_size, prediction_length, num_features)`):
+            Required time features for the prediction window, which the model internally will add to `future_values`.
+            These could be things like "month of year", "day of the month", etc. encoded as vectors (for instance as
+            Fourier features). These could also be so-called "age" features, which basically help the model know "at

+            - 1 for values that are **observed**,
+            - 0 for values that are **missing** (i.e. NaNs that were replaced by zeros).
+
+            This mask is used to filter out missing values for the final loss calculation.
+        attention_mask (`torch.Tensor` of shape `(batch_size, sequence_length)`, *optional*):

+        Greedily generate sequences of sample predictions from a model with a probability distribution head.
+
+        Parameters:
+            past_values (`torch.FloatTensor` of shape `(batch_size, sequence_length)` or `(batch_size, sequence_length, input_size)`):
+                Past values of the time series, that serve as context in order to predict the future. The sequence size
+                of this tensor must be larger than the `context_length` of the model, since the model will use the
+                larger size to construct lag features, i.e. additional values from the past which are added in order to
+                serve as "extra context".
+
+                The `sequence_length` here is equal to `config.context_length` + `max(config.lags_sequence)`, which if
+                no `lags_sequence` is configured, is equal to `config.context_length` + 7 (as by default, the largest
+                look-back index in `config.lags_sequence` is 7). The property `_past_length` returns the actual length
+                of the past.
+
+                The `past_values` is what the Transformer encoder gets as input (with optional additional features,
+                such as `static_categorical_features`, `static_real_features`, `past_time_features` and lags).
+
+                Optionally, missing values need to be replaced with zeros and indicated via the `past_observed_mask`.
+
+                For multivariate time series, the `input_size` > 1 dimension is required and corresponds to the number
+                of variates in the time series per time step.
+            past_time_features (`torch.FloatTensor` of shape `(batch_size, sequence_length, num_features)`):
+                Required time features, which the model internally will add to `past_values`. These could be things
+                like "month of year", "day of the month", etc. encoded as vectors (for instance as Fourier features).
+                These could also be so-called "age" features, which basically help the model know "at which point in
+                life" a time-series is. Age features have small values for distant past time steps and increase
+                monotonically the more we approach the current time step. Holiday features are also a good example of
+                time features.
+
+                These features serve as the "positional encodings" of the inputs. So contrary to a model like BERT,
+                where the position encodings are learned from scratch internally as parameters of the model, the Time
+                Series Transformer requires to provide additional time features. The Time Series Transformer only
+                learns additional embeddings for `static_categorical_features`.
+
+                Additional dynamic real covariates can be concatenated to this tensor, with the caveat that these
+                features must but known at prediction time.
+
+                The `num_features` here is equal to `config.`num_time_features` + `config.num_dynamic_real_features`.
+            future_time_features (`torch.FloatTensor` of shape `(batch_size, prediction_length, num_features)`):
+                Required time features for the prediction window, which the model internally will add to sampled
+                predictions. These could be things like "month of year", "day of the month", etc. encoded as vectors
+                (for instance as Fourier features). These could also be so-called "age" features, which basically help
+                the model know "at which point in life" a time-series is. Age features have small values for distant
+                past time steps and increase monotonically the more we approach the current time step. Holiday features
+                are also a good example of time features.

+                Additional dynamic real covariates can be concatenated to this tensor, with the caveat that these

+
+                The `num_features` here is equal to `config.`num_time_features` + `config.num_dynamic_real_features`.
+            past_observed_mask (`torch.BoolTensor` of shape `(batch_size, sequence_length)` or `(batch_size, sequence_length, input_size)`, *optional*):
+                Boolean mask to indicate which `past_values` were observed and which were missing. Mask values selected
+                in `[0, 1]`:
+
+                - 1 for values that are **observed**,
+                - 0 for values that are **missing** (i.e. NaNs that were replaced by zeros).
+
+            static_categorical_features (`torch.LongTensor` of shape `(batch_size, number of static categorical features)`, *optional*):
+                Optional static categorical features for which the model will learn an embedding, which it will add to
+                the values of the time series.
+
+                Static categorical features are features which have the same value for all time steps (static over
+                time).
+
+                A typical example of a static categorical feature is a time series ID.
+            static_real_features (`torch.FloatTensor` of shape `(batch_size, number of static real features)`, *optional*):
+                Optional static real features which the model will add to the values of the time series.
+
+                Static real features are features which have the same value for all time steps (static over time).
+
+                A typical example of a static real feature is promotion information.
+            output_attentions (`bool`, *optional*):
+                Whether or not to return the attentions tensors of all attention layers.
+            output_hidden_states (`bool`, *optional*):
+                Whether or not to return the hidden states of all layers.
+
+        Return:
+            [`SampleTSPredictionOutput`] where the outputs `sequences` tensor will have shape `(batch_size, number of

+        hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-06):
+            The epsilon used by the layer normalization layers.
+        qkv_bias (`bool`, *optional*, defaults to `True`):
+            Whether to add a bias to the queries, keys and values.
+        attention_type (`str`, *optional*, defaults to `"divided_space_time"`):
+            The attention type to use. Must be one of `"divided_space_time"`, `"space_only"`, `"joint_space_time"`.
+        drop_path_rate (`float`, *optional*, defaults to 0):
+            The dropout ratio for stochastic depth.

+    This is the configuration class to store the configuration for a timm backbone [`TimmBackbone`].
+
+    It is used to instantiate a timm backbone model according to the specified arguments, defining the model.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        backbone (`str`, *optional*):
+            The timm checkpoint to load.
+        num_channels (`int`, *optional*, defaults to 3):
+            The number of input channels.
+        features_only (`bool`, *optional*, defaults to `True`):
+            Whether to output only the features or also the logits.
+        use_pretrained_backbone (`bool`, *optional*, defaults to `True`):
+            Whether to use a pretrained backbone.
+        out_indices (`List[int]`, *optional*):
+            If used as backbone, list of indices of features to output. Can be any of 0, 1, 2, etc. (depending on how
+            many stages the model has). Will default to the last stage if unset.
+        freeze_batch_norm_2d (`bool`, *optional*, defaults to `False`):

+class TrOCRConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`TrOCRForCausalLM`]. It is used to instantiate an
+    TrOCR model according to the specified arguments, defining the model architecture. Instantiating a configuration
+    with the defaults will yield a similar configuration to that of the TrOCR
+    [microsoft/trocr-base-handwritten](https://huggingface.co/microsoft/trocr-base-handwritten) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 50265):
+            Vocabulary size of the TrOCR model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`TrOCRForCausalLM`].
+        d_model (`int`, *optional*, defaults to 1024):
+            Dimensionality of the layers and the pooler layer.
+        decoder_layers (`int`, *optional*, defaults to 12):
+            Number of decoder layers.
+        decoder_attention_heads (`int`, *optional*, defaults to 16):
+            Number of attention heads for each attention layer in the Transformer decoder.
+        decoder_ffn_dim (`int`, *optional*, defaults to 4096):
+            Dimensionality of the "intermediate" (often named feed-forward) layer in decoder.
+        activation_function (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the pooler. If string, `"gelu"`, `"relu"`,
+            `"silu"` and `"gelu_new"` are supported.
+        max_position_embeddings (`int`, *optional*, defaults to 512):
+            The maximum sequence length that this model might ever be used with. Typically set this to something large
+            just in case (e.g., 512 or 1024 or 2048).
+        dropout (`float`, *optional*, defaults to 0.1):
+            The dropout probability for all fully connected layers in the embeddings, and pooler.
+        attention_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        activation_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for activations inside the fully connected layer.
+        init_std (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        decoder_layerdrop (`float`, *optional*, defaults to 0.0):
+            The LayerDrop probability for the decoder. See the [LayerDrop paper](see https://arxiv.org/abs/1909.11556)
+            for more details.
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should return the last key/values attentions (not used by all models).
+        scale_embedding (`bool`, *optional*, defaults to `False`):
+            Whether or not to scale the word embeddings by sqrt(d_model).
+        use_learned_position_embeddings (`bool`, *optional*, defaults to `True`):
+            Whether or not to use learned position embeddings. If not, sinusoidal position embeddings will be used.
+        layernorm_embedding (`bool`, *optional*, defaults to `True`):
+            Whether or not to use a layernorm after the word + position embeddings.
+
+    Example:
+
+    ```python
+    >>> from transformers import TrOCRConfig, TrOCRForCausalLM
+
+    >>> # Initializing a TrOCR-base style configuration
+    >>> configuration = TrOCRConfig()
+
+    >>> # Initializing a model (with random weights) from the TrOCR-base style configuration

+            encoder_hidden_states  (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):

+                if the model is configured as a decoder.
+            encoder_attention_mask (`torch.FloatTensor` of shape `(batch_size, sequence_length)`, *optional*):
+                Mask to avoid performing attention on the padding token indices of the encoder input. This mask is used
+                in the cross-attention if the model is configured as a decoder. Mask values selected in `[0, 1]`:
+            head_mask (`torch.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, *optional*):
+                Mask to nullify selected heads of the attention modules. Mask values selected in `[0, 1]`:
+
+                - 1 indicates the head is **not masked**,
+                - 0 indicates the head is **masked**.
+

+
+                - 1 indicates the head is **not masked**,
+                - 0 indicates the head is **masked**.
+
+            past_key_values (`tuple(tuple(torch.FloatTensor))`, *optional*, returned when `use_cache=True` is passed or when `config.use_cache=True`):
+                Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of
+                shape `(batch_size, num_heads, sequence_length, embed_size_per_head)`) and 2 additional tensors of
+                shape `(batch_size, num_heads, encoder_sequence_length, embed_size_per_head)`. The two additional
+                tensors are only required when the model is used as a decoder in a Sequence to Sequence model.
+
+                Contains pre-computed hidden-states (key and values in the self-attention blocks and in the
+                cross-attention blocks) that can be used (see `past_key_values` input) to speed up sequential decoding.
+
+                If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those
+                that don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of
+                all `decoder_input_ids` of shape `(batch_size, sequence_length)`.
+            labels (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
+                Labels for computing the masked language modeling loss. Indices should either be in `[0, ...,
+                config.vocab_size]` or -100 (see `input_ids` docstring). Tokens with indices set to `-100` are ignored
+                (masked), the loss is only computed for the tokens with labels in `[0, ..., config.vocab_size]`.
+            use_cache (`bool`, *optional*):
+                If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding
+                (see `past_key_values`).
+
+                - 1 for tokens that are **not masked**,
+                - 0 for tokens that are **masked**.
+            output_attentions (`bool`, *optional*):
+                Whether or not to return the attentions tensors of all attention layers. See `attentions` under
+                returned tensors for more detail.
+            output_hidden_states (`bool`, *optional*):
+                Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors
+                for more detail.
+            return_dict (`bool`, *optional*):
+                Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.

+    Arguments:
+        vocab_size (`int`, *optional*, defaults to 33201):
+            Vocabulary size of the UDOP model. Defines the number of different tokens that can be represented by the

+        d_model (`int`, *optional*, defaults to 1024):
+            Size of the encoder layers and the pooler layer.
+        d_kv (`int`, *optional*, defaults to 64):
+            Size of the key, query, value projections per attention head. The `inner_dim` of the projection layer will

+        layer_norm_epsilon (`float`, *optional*, defaults to 1e-06):
+            The epsilon used by the layer normalization layers.
+        initializer_factor (`float`, *optional*, defaults to 1.0):
+            A factor for initializing all weight matrices (should be kept to 1, used internally for initialization
+            testing).
+        feed_forward_proj (`string`, *optional*, defaults to `"relu"`):
+            Type of feed forward layer to be used. Should be one of `"relu"` or `"gated-gelu"`. Udopv1.1 uses the

+        is_encoder_decoder (`bool`, *optional*, defaults to `True`):
+            Whether the model should behave as an encoder/decoder or not.
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should return the last key/values attentions (not used by all models).

+    Constructs a UDOP processor which combines a LayoutLMv3 image processor and a UDOP tokenizer into a single processor.
+
+    [`UdopProcessor`] offers all the functionalities you need to prepare data for the model.
+
+    It first uses [`LayoutLMv3ImageProcessor`] to resize, rescale and normalize document images, and optionally applies OCR
+    to get words and normalized bounding boxes. These are then provided to [`UdopTokenizer`] or [`UdopTokenizerFast`],
+    which turns the words and bounding boxes into token-level `input_ids`, `attention_mask`, `token_type_ids`, `bbox`.
+    Optionally, one can provide integer `word_labels`, which are turned into token-level `labels` for token
+    classification tasks (such as FUNSD, CORD).
+
+    Additionally, it also supports passing `text_target` and `text_pair_target` to the tokenizer, which can be used to
+    prepare labels for language modeling tasks.

+            pad_to_multiple_of (`int`, *optional*):
+                If set will pad the sequence to a multiple of the provided value. This is especially useful to enable

+            The token used is the `sep_token`.
+
+            </Tip>
+
+        unk_token (`str`, *optional*, defaults to `"<unk>"`):
+            The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
+            token instead.
+
+        sep_token (`str`, *optional*, defaults to `"</s>"`):
+            The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for
+            sequence classification or for a text and a question for question answering. It is also used as the last
+            token of a sequence built with special tokens.
+
+        pad_token (`str`, *optional*, defaults to `"<pad>"`):
+            The token used for padding, for example when batching sequences of different lengths.
+        sep_token_box (`List[int]`, *optional*, defaults to `[1000, 1000, 1000, 1000]`):
+            The bounding box to use for the special [SEP] token.
+        pad_token_box (`List[int]`, *optional*, defaults to `[0, 0, 0, 0]`):
+            The bounding box to use for the special [PAD] token.
+        pad_token_label (`int`, *optional*, defaults to -100):
+            The label to use for padding tokens. Defaults to -100, which is the `ignore_index` of PyTorch's
+            CrossEntropyLoss.
+        only_label_first_subword (`bool`, *optional*, defaults to `True`):
+            Whether or not to only label the first subword, in case word labels are provided.
+        additional_special_tokens (`List[str]`, *optional*, defaults to `["<s>NOTUSED", "</s>NOTUSED"]`):
+            Additional special tokens used by the tokenizer.
+
+        sp_model_kwargs (`dict`, *optional*):
+            Will be passed to the `SentencePieceProcessor.__init__()` method. The [Python wrapper for
+            SentencePiece](https://github.com/google/sentencepiece/tree/master/python) can be used, among other things,
+            to set:
+
+            - `enable_sampling`: Enable subword regularization.
+            - `nbest_size`: Sampling parameters for unigram. Invalid for BPE-Dropout.
+
+              - `nbest_size = {0,1}`: No sampling is performed.
+              - `nbest_size > 1`: samples from the nbest_size results.
+              - `nbest_size < 0`: assuming that nbest_size is infinite and samples from the all hypothesis (lattice)
+                using forward-filtering-and-backward-sampling algorithm.
+
+            - `alpha`: Smoothing parameter for unigram sampling, and dropout probability of merge operations for
+              BPE-dropout.
+        legacy (`bool`, *optional*, defaults to `True`):
+            Whether or not the `legacy` behaviour of the tokenizer should be used. Legacy is before the merge of #24622
+            which includes fixes to properly handle tokens that appear after special tokens. A simple example:
+            - `legacy=True`:
+            ```python
+            >>> from transformers import T5Tokenizer
+
+            >>> tokenizer = T5Tokenizer.from_pretrained("t5-base", legacy=True)
+            >>> tokenizer.encode("Hello <extra_id_0>.")
+            [8774, 32099, 3, 5, 1]
+            ```
+            - `legacy=False`:
+            ```python
+            >>> from transformers import T5Tokenizer
+
+            >>> tokenizer = T5Tokenizer.from_pretrained("t5-base", legacy=False)
+            >>> tokenizer.encode("Hello <extra_id_0>.")  # the extra space `[3]` is no longer here
+            [8774, 32099, 5, 1]
+            ```

+            more details.
+        add_prefix_space (`bool`, *optional*, defaults to `True`):
+            Whether or not to add an initial space to the input. This allows to treat the leading word just as any
+            other word.
+
+
+    Attributes:

+    [BPE](https://huggingface.co/docs/tokenizers/python/latest/components.html?highlight=BPE#models).
+
+    This tokenizer inherits from [`PreTrainedTokenizerFast`] which contains most of the main methods. Users should

+            The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for
+            sequence classification or for a text and a question for question answering. It is also used as the last
+            token of a sequence built with special tokens.
+        unk_token (`str`, *optional*, defaults to `"<unk>"`):
+            The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
+            token instead.
+        pad_token (`str`, *optional*, defaults to `"<pad>"`):

+    r"""
+    This is the configuration class to store the configuration of a [`UMT5Model`]. It is used to instantiate a UMT5
+    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
+    defaults will yield a similar configuration to that of the UMT5
+    [google/umt5-small](https://huggingface.co/google/umt5-small) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Arguments:
+        vocab_size (`int`, *optional*, defaults to 250112):
+            Vocabulary size of the UMT5 model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`UMT5Model`] or [`TFUMT5Model`].
+        d_model (`int`, *optional*, defaults to 512):
+            Size of the encoder layers and the pooler layer.
+        d_kv (`int`, *optional*, defaults to 64):
+            Size of the key, query, value projections per attention head. `d_kv` has to be equal to `d_model //
+            num_heads`.
+        d_ff (`int`, *optional*, defaults to 1024):
+            Size of the intermediate feed forward layer in each `UMT5Block`.
+        num_layers (`int`, *optional*, defaults to 8):
+            Number of hidden layers in the Transformer encoder.
+        num_decoder_layers (`int`, *optional*):
+            Number of hidden layers in the Transformer decoder. Will use the same value as `num_layers` if not set.
+        num_heads (`int`, *optional*, defaults to 6):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        relative_attention_num_buckets (`int`, *optional*, defaults to 32):
+            The number of buckets to use for each attention layer.
+        relative_attention_max_distance (`int`, *optional*, defaults to 128):
+            The maximum distance of the longer sequences for the bucket separation.
+        dropout_rate (`float`, *optional*, defaults to 0.1):
+            The ratio for all dropout layers.
+        classifier_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for classifier.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-6):
+            The epsilon used by the layer normalization layers.
+        initializer_factor (`float`, *optional*, defaults to 1):
+            A factor for initializing all weight matrices (should be kept to 1, used internally for initialization
+            testing).
+        feed_forward_proj (`string`, *optional*, defaults to `"gated-gelu"`):
+            Type of feed forward layer to be used. Should be one of `"relu"` or `"gated-gelu"`.
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should return the last key/values attentions (not used by all models).

+Convert T5X checkpoint to PyTorch
+
+Steps:
+- Install gsutil according to https://cloud.google.com/storage/docs/gsutil_install
+- Get a T5X checkpoint at https://github.com/google-research/t5x/blob/main/docs/models.md#t5-11-checkpoints Example:
+    `gsutil -m cp -r gs://t5-data/pretrained_models/t5x/t5_1_1_small $HOME/`
+- Create or download a corresponding config for the downloaded model. E.g. for T5 v1.1 small, you can use
+    https://huggingface.co/google/t5-v1_1-small/blob/main/config.json
+- Convert:
+    ```
+    python3 convert_t5x_checkpoint_to_pytorch.py --t5x_checkpoint_path=$HOME/t5_1_1_small --config_file=config.json\
+      --pytorch_dump_path=$HOME/t5_1_1_small_pt

+    Narang, Michael Matena, Yanqi Zhou, Wei Li, Peter J. Liu. It's an encoder decoder transformer pre-trained in a
+    text-to-text denoising generative setting.
+
+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass.
+    Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
+    and behavior.
+
+    Parameters:
+        config ([`UMT5Config`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the

+    Michael Zeng, Xuedong Huang.
+
+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving etc.).
+
+    This model is a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) sub-class. Use
+    it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage and
+    behavior.
+
+    Parameters:
+        config ([`UniSpeechConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+    Args:
+        input_values (`torch.FloatTensor` of shape `(batch_size, sequence_length)`):
+            Float values of input raw speech waveform. Values can be obtained by loading a `.flac` or `.wav` audio file
+            into an array of type `List[float]` or a `numpy.ndarray`, *e.g.* via the soundfile library (`pip install
+            soundfile`). To prepare the array into `input_values`, the [`AutoProcessor`] should be used for padding and
+            conversion into a tensor of type `torch.FloatTensor`. See [`Wav2Vec2Processor.__call__`] for details.
+        attention_mask (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Mask to avoid performing convolution and attention on padding token indices. Mask values selected in `[0,
+            1]`:
+
+            - 1 for tokens that are **not masked**,
+            - 0 for tokens that are **masked**.
+

+

+            **not** be passed to avoid degraded performance when doing batched inference. For such models
+            `input_values` should simply be padded with 0 and passed without `attention_mask`. Be aware that these
+            models also yield slightly different results depending on whether `input_values` is padded or not.

+class UnivNetConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`UnivNetModel`]. It is used to instantiate a
+    UnivNet vocoder model according to the specified arguments, defining the model architecture. Instantiating a
+    configuration with the defaults will yield a similar configuration to that of the UnivNet
+    [dg845/univnet-dev](https://huggingface.co/dg845/univnet-dev) architecture, which corresponds to the 'c32'
+    architecture in [maum-ai/univnet](https://github.com/maum-ai/univnet/blob/master/config/default_c32.yaml).
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        model_in_channels (`int`, *optional*, defaults to 64):
+            The number of input channels for the UnivNet residual network. This should correspond to
+            `noise_sequence.shape[1]` and the value used in the [`UnivNetFeatureExtractor`] class.
+        model_hidden_channels (`int`, *optional*, defaults to 32):
+            The number of hidden channels of each residual block in the UnivNet residual network.
+        num_mel_bins (`int`, *optional*, defaults to 100):
+            The number of frequency bins in the conditioning log-mel spectrogram. This should correspond to the value
+            used in the [`UnivNetFeatureExtractor`] class.
+        resblock_kernel_sizes (`Tuple[int]` or `List[int]`, *optional*, defaults to `[3, 3, 3]`):
+            A tuple of integers defining the kernel sizes of the 1D convolutional layers in the UnivNet residual
+            network. The length of `resblock_kernel_sizes` defines the number of resnet blocks and should match that of
+            `resblock_stride_sizes` and `resblock_dilation_sizes`.
+        resblock_stride_sizes (`Tuple[int]` or `List[int]`, *optional*, defaults to `[8, 8, 4]`):
+            A tuple of integers defining the stride sizes of the 1D convolutional layers in the UnivNet residual
+            network. The length of `resblock_stride_sizes` should match that of `resblock_kernel_sizes` and
+            `resblock_dilation_sizes`.
+        resblock_dilation_sizes (`Tuple[Tuple[int]]` or `List[List[int]]`, *optional*, defaults to `[[1, 3, 9, 27], [1, 3, 9, 27], [1, 3, 9, 27]]`):
+            A nested tuple of integers defining the dilation rates of the dilated 1D convolutional layers in the
+            UnivNet residual network. The length of `resblock_dilation_sizes` should match that of
+            `resblock_kernel_sizes` and `resblock_stride_sizes`. The length of each nested list in
+            `resblock_dilation_sizes` defines the number of convolutional layers per resnet block.
+        kernel_predictor_num_blocks (`int`, *optional*, defaults to 3):
+            The number of residual blocks in the kernel predictor network, which calculates the kernel and bias for
+            each location variable convolution layer in the UnivNet residual network.
+        kernel_predictor_hidden_channels (`int`, *optional*, defaults to 64):
+            The number of hidden channels for each residual block in the kernel predictor network.
+        kernel_predictor_conv_size (`int`, *optional*, defaults to 3):
+            The kernel size of each 1D convolutional layer in the kernel predictor network.
+        kernel_predictor_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout probability for each residual block in the kernel predictor network.
+        initializer_range (`float`, *optional*, defaults to 0.01):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        leaky_relu_slope (`float`, *optional*, defaults to 0.2):
+            The angle of the negative slope used by the leaky ReLU activation.
+
+    Example:
+
+    ```python
+    >>> from transformers import UnivNetModel, UnivNetConfig
+
+    >>> # Initializing a Tortoise TTS style configuration
+    >>> configuration = UnivNetConfig()
+
+    >>> # Initializing a model (with random weights) from the Tortoise TTS style configuration
+    >>> model = UnivNetModel(configuration)
+
+    >>> # Accessing the model configuration
+    >>> configuration = model.config

+class UnivNetFeatureExtractor(SequenceFeatureExtractor):
+    r"""
+    Constructs a UnivNet feature extractor.
+
+    This class extracts log-mel-filter bank features from raw speech using the short time Fourier Transform (STFT). The
+    STFT implementation follows that of TacoTron 2 and Hifi-GAN.
+
+    This feature extractor inherits from [`~feature_extraction_sequence_utils.SequenceFeatureExtractor`] which contains
+    most of the main methods. Users should refer to this superclass for more information regarding those methods.
+
+    Args:
+        feature_size (`int`, *optional*, defaults to 1):
+            The feature dimension of the extracted features.
+        sampling_rate (`int`, *optional*, defaults to 24000):
+            The sampling rate at which the audio files should be digitalized expressed in hertz (Hz).
+        padding_value (`float`, *optional*, defaults to 0.0):
+            The value to pad with when applying the padding strategy defined by the `padding` argument to
+            [`UnivNetFeatureExtractor.__call__`]. Should correspond to audio silence. The `pad_end` argument to
+            `__call__` will also use this padding value.
+        do_normalize (`bool`, *optional*, defaults to `False`):
+            Whether to perform Tacotron 2 normalization on the input. Normalizing can help to significantly improve the
+            performance for some models.
+        num_mel_bins (`int`, *optional*, defaults to 100):
+            The number of mel-frequency bins in the extracted spectrogram features. This should match
+            `UnivNetModel.config.num_mel_bins`.
+        hop_length (`int`, *optional*, defaults to 256):
+            The direct number of samples between sliding windows. Otherwise referred to as "shift" in many papers. Note
+            that this is different from other audio feature extractors such as [`SpeechT5FeatureExtractor`] which take
+            the `hop_length` in ms.
+        win_length (`int`, *optional*, defaults to 1024):
+            The direct number of samples for each sliding window. Note that this is different from other audio feature
+            extractors such as [`SpeechT5FeatureExtractor`] which take the `win_length` in ms.
+        win_function (`str`, *optional*, defaults to `"hann_window"`):
+            Name for the window function used for windowing, must be accessible via `torch.{win_function}`
+        filter_length (`int`, *optional*, defaults to 1024):
+            The number of FFT components to use. If `None`, this is determined using
+            `transformers.audio_utils.optimal_fft_length`.
+        max_length_s (`int`, *optional*, defaults to 10):
+            The maximum input lenght of the model in seconds. This is used to pad the audio.
+        fmin (`float`, *optional*, defaults to 0.0):
+            Minimum mel frequency in Hz.
+        fmax (`float`, *optional*):
+            Maximum mel frequency in Hz. If not set, defaults to `sampling_rate / 2`.
+        mel_floor (`float`, *optional*, defaults to 1e-09):
+            Minimum value of mel frequency banks. Note that the way [`UnivNetFeatureExtractor`] uses `mel_floor` is
+            different than in [`transformers.audio_utils.spectrogram`].
+        center (`bool`, *optional*, defaults to `False`):
+            Whether to pad the waveform so that frame `t` is centered around time `t * hop_length`. If `False`, frame
+            `t` will start at time `t * hop_length`.
+        compression_factor (`float`, *optional*, defaults to 1.0):
+            The multiplicative compression factor for dynamic range compression during spectral normalization.
+        compression_clip_val (`float`, *optional*, defaults to 1e-05):
+            The clip value applied to the waveform before applying dynamic range compression during spectral
+            normalization.
+        normalize_min (`float`, *optional*, defaults to -11.512925148010254):
+            The min value used for Tacotron 2-style linear normalization. The default is the original value from the
+            Tacotron 2 implementation.
+        normalize_max (`float`, *optional*, defaults to 2.3143386840820312):
+            The max value used for Tacotron 2-style linear normalization. The default is the original value from the
+            Tacotron 2 implementation.
+        model_in_channels (`int`, *optional*, defaults to 64):
+            The number of input channels to the [`UnivNetModel`] model. This should match
+            `UnivNetModel.config.model_in_channels`.
+        pad_end_length (`int`, *optional*, defaults to 10):
+            If padding the end of each waveform, the number of spectrogram frames worth of samples to append. The
+            number of appended samples will be `pad_end_length * hop_length`.
+        return_attention_mask (`bool`, *optional*, defaults to `True`):
+            Whether or not [`~UnivNetFeatureExtractor.__call__`] should return `attention_mask`.

+    This is the configuration class to store the configuration of a [`VideoLlavaForConditionalGeneration`]. It is used to instantiate an
+    VideoLlava model according to the specified arguments, defining the model architecture. Instantiating a configuration
+    with the defaults will yield a similar configuration to that of the like LanguageBind/Video-LLaVA-7B-hf.

+            Custom vision config or dict. Defaults to `CLIPVisionConfig` if not indicated.
+        text_config (`Union[AutoConfig, dict]`, *optional*):
+            The config object of the text backbone. Can be any of `LlamaConfig` or `MistralConfig`.

+        video_token_index (`int`, *optional*, defaults to 32001):
+            The video token index to encode the image prompt.
+        projector_hidden_act (`str`, *optional*, defaults to `"gelu"`):
+            The activation function used by the multimodal projector.
+        vision_feature_select_strategy (`str`, *optional*, defaults to `"default"`):
+            The feature selection strategy used to select the vision feature from the CLIP backbone.
+            Can be either "full" to select all features or "default" to select features without `CLS`.
+        vision_feature_layer (`Union[int, List[int]]`, *optional*, defaults to -2):
+            The index of the layer to select the vision feature. If multiple indices are provided,
+            the vision feature of the corresponding indices will be concatenated to form the
+            vision features.
+        image_seq_length (`int`, *optional*, defaults to 256):
+            Sequence length of one image embedding.
+        video_seq_length (`int`, *optional*, defaults to 2056):
+            Sequence length of one video embedding.
+        multimodal_projector_bias (`bool`, *optional*, defaults to `True`):

+        pixel_values_videos (`torch.FloatTensor` of shape `(batch_size, num_frames, num_channels, image_size, image_size)):
+            The tensors corresponding to the input video. Pixel values can be obtained using
+            [`AutoImageProcessor`]. See [`VideoLlavaImageProcessor.__call__`] for details ([]`LlavaProcessor`] uses
+            [`VideoLlavaImageProcessor`] for processing videos).
+        attention_mask (`torch.Tensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
+
+            - 1 for tokens that are **not masked**,
+            - 0 for tokens that are **masked**.
+
+            [What are attention masks?](../glossary#attention-mask)
+
+            Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.encode`] and
+            [`PreTrainedTokenizer.__call__`] for details.
+
+            If `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
+            `past_key_values`).
+
+            If you want to change padding behavior, you should read [`modeling_opt._prepare_decoder_attention_mask`]
+            and modify to your needs. See diagram 1 in [the paper](https://arxiv.org/abs/1910.13461) for more
+            information on the default strategy.
+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
+        position_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Indices of positions of each input sequence tokens in the position embeddings. Selected in the range `[0,
+            config.n_positions - 1]`. [What are position IDs?](../glossary#position-ids)
+        past_key_values (`tuple(tuple(torch.FloatTensor))`, *optional*, returned when `use_cache=True` is passed or when `config.use_cache=True`):
+            Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of shape
+            `(batch_size, num_heads, sequence_length, embed_size_per_head)`) and 2 additional tensors of shape
+            `(batch_size, num_heads, encoder_sequence_length, embed_size_per_head)`.
+
+            Contains pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention
+            blocks) that can be used (see `past_key_values` input) to speed up sequential decoding.
+
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
+            don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all
+            `decoder_input_ids` of shape `(batch_size, sequence_length)`.
+        inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
+            model's internal embedding lookup matrix.
+        vision_feature_layer (`Union[int, List[int]], *optional*, defaults to -2`):
+            The index of the layer to select the vision feature. If multiple indices are provided,
+            the vision feature of the corresponding indices will be concatenated to form the
+            vision features.
+        vision_feature_select_strategy (`str`, *optional*, defaults to `"default"`):
+            The feature selection strategy used to select the vision feature from the vision backbone.
+            Can be one of `"default"` or `"full"`
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+            `past_key_values`).
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail.
+        return_dict (`bool`, *optional*):
+            Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.
+        cache_position (`torch.LongTensor` of shape `(sequence_length)`, *optional*):
+            Indices depicting the position of the input sequence tokens in the sequence. Contrarily to `position_ids`,
+            this tensor is not affected by padding. It is used to update the cache in the correct position and to infer
+            the complete sequence length.

+    with the defaults will yield a similar configuration to that of the VideoMAE
+    [MCG-NJU/videomae-base](https://huggingface.co/MCG-NJU/videomae-base) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+

+class ViltConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`ViLTModel`]. It is used to instantiate an ViLT
+    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
+    defaults will yield a similar configuration to that of the ViLT
+    [dandelin/vilt-b32-mlm](https://huggingface.co/dandelin/vilt-b32-mlm) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 30522):
+            Vocabulary size of the text part of the model. Defines the number of different tokens that can be
+            represented by the `inputs_ids` passed when calling [`ViltModel`].
+        type_vocab_size (`int`, *optional*, defaults to 2):
+            The vocabulary size of the `token_type_ids` passed when calling [`ViltModel`]. This is used when encoding
+            text.
+        modality_type_vocab_size (`int`, *optional*, defaults to 2):
+            The vocabulary size of the modalities passed when calling [`ViltModel`]. This is used after concatening the
+            embeddings of the text and image modalities.
+        max_position_embeddings (`int`, *optional*, defaults to 40):
+            The maximum sequence length that this model might ever be used with.
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimensionality of the encoder layers and the pooler layer.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        intermediate_size (`int`, *optional*, defaults to 3072):
+            Dimensionality of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"selu"` and `"gelu_new"` are supported.
+        hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-12):
+            The epsilon used by the layer normalization layers.
+        image_size (`int`, *optional*, defaults to 384):
+            The size (resolution) of each image.
+        patch_size (`int`, *optional*, defaults to 32):
+            The size (resolution) of each patch.
+        num_channels (`int`, *optional*, defaults to 3):
+            The number of input channels.
+        qkv_bias (`bool`, *optional*, defaults to `True`):
+            Whether to add a bias to the queries, keys and values.
+        max_image_length (`int`, *optional*, defaults to -1):
+            The maximum number of patches to take as input for the Transformer encoder. If set to a positive integer,
+            the encoder will sample `max_image_length` patches at maximum. If set to -1, will not be taken into
+            account.
+        num_images (`int`, *optional*, defaults to -1):
+            The number of images to use for natural language visual reasoning. If set to a positive integer, will be
+            used by [`ViltForImagesAndTextClassification`] for defining the classifier head.
+
+    Example:
+
+    ```python
+    >>> from transformers import ViLTModel, ViLTConfig
+
+    >>> # Initializing a ViLT dandelin/vilt-b32-mlm style configuration
+    >>> configuration = ViLTConfig()

+
+            Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.encode`] and
+            [`PreTrainedTokenizer.__call__`] for details.

+            [`AutoImageProcessor`]. See [`CLIPImageProcessor.__call__`] for details ([]`LlavaProcessor`] uses
+            [`CLIPImageProcessor`] for processing images).
+        attention_mask (`torch.Tensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
+
+            - 1 for tokens that are **not masked**,
+            - 0 for tokens that are **masked**.
+
+            [What are attention masks?](../glossary#attention-mask)
+
+            Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.encode`] and
+            [`PreTrainedTokenizer.__call__`] for details.
+
+            If `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
+            `past_key_values`).
+
+            If you want to change padding behavior, you should read [`modeling_opt._prepare_decoder_attention_mask`]
+            and modify to your needs. See diagram 1 in [the paper](https://arxiv.org/abs/1910.13461) for more

+        position_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):

+            `(batch_size, num_heads, encoder_sequence_length, embed_size_per_head)`.
+
+            Contains pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention
+            blocks) that can be used (see `past_key_values` input) to speed up sequential decoding.
+
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
+            don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all
+            `decoder_input_ids` of shape `(batch_size, sequence_length)`.
+        inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
+            model's internal embedding lookup matrix.
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+            `past_key_values`).
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail.
+        return_dict (`bool`, *optional*):
+            Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.
+        cache_position (`torch.LongTensor` of shape `(sequence_length)`, *optional*):
+            Indices depicting the position of the input sequence tokens in the sequence. Contrarily to `position_ids`,
+            this tensor is not affected by padding. It is used to update the cache in the correct position and to infer

+    This class can be used to initialize an image-to-text-sequence model with any pretrained vision autoencoding model
+    as the encoder and any pretrained text autoregressive model as the decoder. The encoder is loaded via
+    [`~AutoModel.from_pretrained`] function and the decoder is loaded via [`~AutoModelForCausalLM.from_pretrained`]
+    function. Cross-attention layers are automatically added to the decoder and should be fine-tuned on a downstream
+    generative task, like image captioning.
+
+    The effectiveness of initializing sequence-to-sequence models with pretrained checkpoints for sequence generation
+    tasks was shown in [Leveraging Pre-trained Checkpoints for Sequence Generation
+    Tasks](https://arxiv.org/abs/1907.12461) by Sascha Rothe, Shashi Narayan, Aliaksei Severyn. Michael Matena, Yanqi
+    Zhou, Wei Li, Peter J. Liu.
+
+    Additionally, in [TrOCR: Transformer-based Optical Character Recognition with Pre-trained
+    Models](https://arxiv.org/abs/2109.10282) it is shown how leveraging large pretrained vision models for optical
+    character recognition (OCR) yields a significant performance improvement.
+
+    After such a Vision-Encoder-Text-Decoder model has been trained/fine-tuned, it can be saved/loaded just like any
+    other models (see the examples for more information).
+
+    This model inherits from [`FlaxPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a Flax Linen
+    [flax.nn.Module](https://flax.readthedocs.io/en/latest/_autosummary/flax.nn.module.html) subclass. Use it as a
+    regular Flax Module and refer to the Flax documentation for all matter related to general usage and behavior.
+
+    Parameters:
+        config ([`VisionEncoderDecoderConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~FlaxPreTrainedModel.from_pretrained`] method to load the model weights.
+        dtype (`jax.numpy.dtype`, *optional*, defaults to `jax.numpy.float32`):
+            The data type of the computation. Can be one of `jax.numpy.float32`, `jax.numpy.float16` (on GPUs) and
+            `jax.numpy.bfloat16` (on TPUs).
+
+            This can be used to enable mixed-precision training or half-precision inference on GPUs or TPUs. If
+            specified all the computation will be performed with the given `dtype`.
+
+            **Note that this only specifies the dtype of the computation and does not influence the dtype of model
+            parameters.**
+
+            If you wish to change the dtype of the model parameters, see [`~FlaxPreTrainedModel.to_fp16`] and
+            [`~FlaxPreTrainedModel.to_bf16`].

+    This class can be used to initialize an image-to-text-sequence model with any pretrained vision autoencoding model
+    as the encoder and any pretrained text autoregressive model as the decoder. The encoder is loaded via
+    [`~TFAutoModel.from_pretrained`] function and the decoder is loaded via [`~TFAutoModelForCausalLM.from_pretrained`]
+    function. Cross-attention layers are automatically added to the decoder and should be fine-tuned on a downstream
+    generative task, like image captioning.
+
+    The effectiveness of initializing sequence-to-sequence models with pretrained checkpoints for sequence generation
+    tasks was shown in [Leveraging Pre-trained Checkpoints for Sequence Generation
+    Tasks](https://arxiv.org/abs/1907.12461) by Sascha Rothe, Shashi Narayan, Aliaksei Severyn. Michael Matena, Yanqi
+    Zhou, Wei Li, Peter J. Liu.
+
+    Additionally, in [TrOCR: Transformer-based Optical Character Recognition with Pre-trained
+    Models](https://arxiv.org/abs/2109.10282) it is shown how leveraging large pretrained vision models for optical
+    character recognition (OCR) yields a significant performance improvement.
+
+    After such a Vision-Encoder-Text-Decoder model has been trained/fine-tuned, it can be saved/loaded just like any
+    other models (see the examples for more information).
+
+    This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it
+    as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and
+    behavior.
+
+    Parameters:
+        config ([`VisionEncoderDecoderConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~TFPreTrainedModel.from_pretrained`] method to load the model weights.

+VISION_ENCODER_DECODER_INPUTS_DOCSTRING = r"""
+    Args:
+        pixel_values (`np.ndarray`, `tf.Tensor`, `List[tf.Tensor]` ``Dict[str, tf.Tensor]` or `Dict[str, np.ndarray]` and each example must have the shape `(batch_size, num_channels, height, width)`):
+            Pixel values. Pixel values can be obtained using the vision's model's image processor. For example, using
+            [`AutoImageProcessor`]. See [`ViTImageProcessor.__call__`] for details.
+        decoder_input_ids (`np.ndarray` or `tf.Tensor` of shape `(batch_size, target_sequence_length)`, *optional*):
+            Indices of decoder input sequence tokens in the vocabulary.
+
+            Indices can be obtained using [`PreTrainedTokenizer`]. See [`PreTrainedTokenizer.encode`] and
+            [`PreTrainedTokenizer.__call__`] for details.
+
+            [What are input IDs?](../glossary#input-ids)
+
+            If `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
+            `past_key_values`).
+
+            Provide for sequence to sequence training to the decoder. Indices can be obtained using
+            [`PreTrainedTokenizer`]. See [`PreTrainedTokenizer.encode`] and [`PreTrainedTokenizer.__call__`] for
+            details.
+        decoder_attention_mask (`np.ndarray` or `tf.Tensor` of shape `(batch_size, target_sequence_length)`, *optional*):
+            Default behavior: generate a tensor that ignores pad tokens in `decoder_input_ids`. Causal mask will also
+            be used by default.
+        encoder_outputs (`tuple(tuple(tf.Tensor)`, *optional*):
+            This tuple must consist of (`last_hidden_state`, *optional*: `hidden_states`, *optional*: `attentions`)
+            `last_hidden_state` (`tf.Tensor` of shape `({0}, hidden_size)`) is a tensor of hidden-states at the output
+            of the last layer of the encoder. Used in the cross-attention of the decoder.
+        past_key_values (`tuple(tuple(tf.Tensor))` of length `config.n_layers` with each tuple having 4 tensors of shape `(batch_size, num_heads, sequence_length - 1, embed_size_per_head)`):
+            Contains precomputed key and value hidden states of the attention blocks. Can be used to speed up decoding.
+
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
+            don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all
+            `decoder_input_ids` of shape `({0})`.
+        decoder_inputs_embeds (`np.ndarray` or `tf.Tensor` of shape `(batch_size, target_sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `decoder_input_ids` you can choose to directly pass an embedded
+            representation. This is useful if you want more control over how to convert `decoder_input_ids` indices
+            into associated vectors than the model's internal embedding lookup matrix.
+        labels (`np.ndarray` or `tf.Tensor` of shape `({0})`, *optional*):
+            Labels for computing the masked language modeling loss for the decoder. Indices should be in `[-100, 0,
+            ..., config.vocab_size]` (see `input_ids` docstring) Tokens with indices set to `-100` are ignored
+            (masked), the loss is only computed for the tokens with labels in `[0, ..., config.vocab_size]`
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+            `past_key_values`).
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail.
+        return_dict (`bool`, *optional*):
+            If set to `True`, the model will return a [`~utils.Seq2SeqLMOutput`] instead of a plain tuple.
+        training (`bool`, *optional*, defaults to `False`):
+            Whether or not to use the model in training mode (some modules like dropout modules have different
+            behaviors between training and evaluation).
+        kwargs (*optional*): Remaining dictionary of keyword arguments. Keyword arguments come in two flavors:
+
+            - Without a prefix which will be input as `**encoder_kwargs` for the encoder forward function.
+            - With a *decoder_* prefix which will be input as `**decoder_kwargs` for the decoder forward function.

+                    - A path to a *directory* containing model weights saved using
+                      [`~TFPreTrainedModel.save_pretrained`], e.g., `./my_model_directory/`.
+                    - A path or url to a *pytorch index checkpoint file* (e.g, `./pt_model/`). In this case,

+
+            kwargs (remaining dictionary of keyword arguments, *optional*):
+                Can be used to update the configuration object (after it being loaded) and initiate the model (e.g.,

+
+                - To update the encoder configuration, use the prefix *encoder_* for each configuration parameter.

+    This class can be used to initialize an image-to-text-sequence model with any pretrained vision autoencoding model
+    as the encoder and any pretrained text autoregressive model as the decoder. The encoder is loaded via
+    [`~AutoModel.from_pretrained`] function and the decoder is loaded via [`~AutoModelForCausalLM.from_pretrained`]
+    function. Cross-attention layers are automatically added to the decoder and should be fine-tuned on a downstream
+    generative task, like image captioning.
+
+    The effectiveness of initializing sequence-to-sequence models with pretrained checkpoints for sequence generation
+    tasks was shown in [Leveraging Pre-trained Checkpoints for Sequence Generation
+    Tasks](https://arxiv.org/abs/1907.12461) by Sascha Rothe, Shashi Narayan, Aliaksei Severyn. Michael Matena, Yanqi
+    Zhou, Wei Li, Peter J. Liu.
+
+    Additionally, in [TrOCR: Transformer-based Optical Character Recognition with Pre-trained
+    Models](https://arxiv.org/abs/2109.10282) it is shown how leveraging large pretrained vision models for optical
+    character recognition (OCR) yields a significant performance improvement.
+
+    After such a Vision-Encoder-Text-Decoder model has been trained/fine-tuned, it can be saved/loaded just like any
+    other models (see the examples for more information).
+
+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass.
+    Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
+    and behavior.
+
+    Parameters:
+        config ([`VisionEncoderDecoderConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+
+VISION_ENCODER_DECODER_INPUTS_DOCSTRING = r"""
+    Args:
+        pixel_values (`torch.FloatTensor` of shape `(batch_size, num_channels, height, width)`):
+            Pixel values. Pixel values can be obtained using an image processor (e.g. if you use ViT as the encoder,
+            you should use [`AutoImageProcessor`]). See [`ViTImageProcessor.__call__`] for details.
+        decoder_input_ids (`torch.LongTensor` of shape `(batch_size, target_sequence_length)`, *optional*):
+            Indices of decoder input sequence tokens in the vocabulary.
+
+            Indices can be obtained using [`PreTrainedTokenizer`]. See [`PreTrainedTokenizer.encode`] and
+            [`PreTrainedTokenizer.__call__`] for details.
+
+            [What are input IDs?](../glossary#input-ids)
+
+            If `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
+            `past_key_values`).
+
+            For training, `decoder_input_ids` are automatically created by the model by shifting the `labels` to the
+            right, replacing -100 by the `pad_token_id` and prepending them with the `decoder_start_token_id`.
+        decoder_attention_mask (`torch.BoolTensor` of shape `(batch_size, target_sequence_length)`, *optional*):
+            Default behavior: generate a tensor that ignores pad tokens in `decoder_input_ids`. Causal mask will also
+            be used by default.
+        encoder_outputs (`tuple(torch.FloatTensor)`, *optional*):
+            This tuple must consist of (`last_hidden_state`, *optional*: `hidden_states`, *optional*: `attentions`)
+            `last_hidden_state` (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`) is a tensor
+            of hidden-states at the output of the last layer of the encoder. Used in the cross-attention of the
+            decoder.
+        past_key_values (`tuple(tuple(torch.FloatTensor))` of length `config.n_layers` with each tuple having 4 tensors of shape `(batch_size, num_heads, sequence_length - 1, embed_size_per_head)`):
+            Contains precomputed key and value hidden states of the attention blocks. Can be used to speed up decoding.
+
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
+            don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all
+            `decoder_input_ids` of shape `(batch_size, sequence_length)`.
+        decoder_inputs_embeds (`torch.FloatTensor` of shape `(batch_size, target_sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `decoder_input_ids` you can choose to directly pass an embedded
+            representation. This is useful if you want more control over how to convert `decoder_input_ids` indices
+            into associated vectors than the model's internal embedding lookup matrix.
+        labels (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Labels for computing the masked language modeling loss for the decoder. Indices should be in `[-100, 0,
+            ..., config.vocab_size]` (see `input_ids` docstring) Tokens with indices set to `-100` are ignored
+            (masked), the loss is only computed for the tokens with labels in `[0, ..., config.vocab_size]`
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+            `past_key_values`).
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail.
+        return_dict (`bool`, *optional*):
+            If set to `True`, the model will return a [`~utils.Seq2SeqLMOutput`] instead of a plain tuple.
+        kwargs (*optional*): Remaining dictionary of keyword arguments. Keyword arguments come in two flavors:
+
+            - Without a prefix which will be input as `**encoder_kwargs` for the encoder forward function.
+            - With a *decoder_* prefix which will be input as `**decoder_kwargs` for the decoder forward function.

+        Instantiate an encoder and a decoder from one or two base classes of the library from pretrained model
+        checkpoints.
+
+
+        The model is set in evaluation mode by default using `model.eval()` (Dropout modules are deactivated). To train
+        the model, you need to first set it back in training mode with `model.train()`.
+
+        Params:
+            encoder_pretrained_model_name_or_path (`str`, *optional*):
+                Information necessary to initiate the image encoder. Can be either:
+
+                    - A string, the *model id* of a pretrained model hosted inside a model repo on huggingface.co. An
+                      example is `google/vit-base-patch16-224-in21k`.
+                    - A path to a *directory* containing model weights saved using
+                      [`~PreTrainedModel.save_pretrained`], e.g., `./my_model_directory/`.
+                    - A path or url to a *tensorflow index checkpoint file* (e.g, `./tf_model/model.ckpt.index`). In
+                      this case, `from_tf` should be set to `True` and a configuration object should be provided as
+                      `config` argument. This loading path is slower than converting the TensorFlow checkpoint in a
+                      PyTorch model using the provided conversion scripts and loading the PyTorch model afterwards.
+
+            decoder_pretrained_model_name_or_path (`str`, *optional*, defaults to `None`):
+                Information necessary to initiate the text decoder. Can be either:
+
+                    - A string, the *model id* of a pretrained model hosted inside a model repo on huggingface.co.
+                    - A path to a *directory* containing model weights saved using
+                      [`~PreTrainedModel.save_pretrained`], e.g., `./my_model_directory/`.
+                    - A path or url to a *tensorflow index checkpoint file* (e.g, `./tf_model/model.ckpt.index`). In
+                      this case, `from_tf` should be set to `True` and a configuration object should be provided as

+
+            model_args (remaining positional arguments, *optional*):
+                All remaning positional arguments will be passed to the underlying model's `__init__` method.
+
+            kwargs (remaining dictionary of keyword arguments, *optional*):
+                Can be used to update the configuration object (after it being loaded) and initiate the model (e.g.,
+                `output_attentions=True`).
+
+                - To update the encoder configuration, use the prefix *encoder_* for each configuration parameter.
+                - To update the decoder configuration, use the prefix *decoder_* for each configuration parameter.
+                - To update the parent model configuration, do not use a prefix for each configuration parameter.
+
+                Behaves differently depending on whether a `config` is provided or automatically loaded.

+    This class can be used to initialize a vision-text dual encoder model with any pretrained vision autoencoding model
+    as the vision encoder and any pretrained text model as the text encoder. The vision and text encoders are loaded
+    via the [`~FlaxAutoModel.from_pretrained`] method. The projection layers are automatically added to the model and
+    should be fine-tuned on a downstream task, like contrastive image-text modeling.
+
+    In [LiT: Zero-Shot Transfer with Locked-image Text Tuning](https://arxiv.org/abs/2111.07991) it is shown how
+    leveraging pre-trained (locked/frozen) image and text model for contrastive learning yields significant improvment
+    on new zero-shot vision tasks such as image classification or retrieval.
+
+    After such a Vision-Text-Dual-Encoder model has been trained/fine-tuned, it can be saved/loaded just like any other
+    models (see the examples for more information).
+
+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+     This model is also a
+     [flax.linen.Module](https://flax.readthedocs.io/en/latest/api_reference/flax.linen/module.html) subclass. Use it
+     as a regular Flax linen Module and refer to the Flax documentation for all matter related to general usage and
+     behavior.
+
+    Finally, this model supports inherent JAX features such as:
+
+    - [Just-In-Time (JIT) compilation](https://jax.readthedocs.io/en/latest/jax.html#just-in-time-compilation-jit)
+    - [Automatic Differentiation](https://jax.readthedocs.io/en/latest/jax.html#automatic-differentiation)
+    - [Vectorization](https://jax.readthedocs.io/en/latest/jax.html#vectorization-vmap)
+    - [Parallelization](https://jax.readthedocs.io/en/latest/jax.html#parallelization-pmap)
+
+    Parameters:
+        config ([`VisionTextDualEncoderConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~FlaxPreTrainedModel.from_pretrained`] method to load the model weights.
+        dtype (`jax.numpy.dtype`, *optional*, defaults to `jax.numpy.float32`):
+            The data type of the computation. Can be one of `jax.numpy.float32`, `jax.numpy.float16` (on GPUs) and
+            `jax.numpy.bfloat16` (on TPUs).
+
+            This can be used to enable mixed-precision training or half-precision inference on GPUs or TPUs. If
+            specified all the computation will be performed with the given `dtype`.
+
+            **Note that this only specifies the dtype of the computation and does not influence the dtype of model
+            parameters.**
+
+            If you wish to change the dtype of the model parameters, see [`~FlaxPreTrainedModel.to_fp16`] and
+            [`~FlaxPreTrainedModel.to_bf16`].

+    This class can be used to initialize a vision-text dual encoder model with any pretrained vision autoencoding model
+    as the vision encoder and any pretrained text model as the text encoder. The vision and text encoders are loaded
+    via the [`~TFAutoModel.from_pretrained`] method. The projection layers are automatically added to the model and
+    should be fine-tuned on a downstream task, like contrastive image-text modeling.
+
+    In [LiT: Zero-Shot Transfer with Locked-image Text Tuning](https://arxiv.org/abs/2111.07991) it is shown how
+    leveraging pre-trained (locked/frozen) image and text model for contrastive learning yields significant improvment
+    on new zero-shot vision tasks such as image classification or retrieval.
+
+    After such a Vision-Text-Dual-Encoder model has been trained/fine-tuned, it can be saved/loaded just like any other
+    models (see the examples for more information).
+
+    This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a Keras [Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it as a
+    regular Keras Model and refer to the TF documentation for all matter related to general usage and behavior.
+
+    Parameters:
+        config ([`VisionEncoderDecoderConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~TFPreTrainedModel.from_pretrained`] method to load the model weights.

+
+                - To update the text configuration, use the prefix *text_* for each configuration parameter.

+    This class can be used to initialize a vision-text dual encoder model with any pretrained vision autoencoding model
+    as the vision encoder and any pretrained text model as the text encoder. The vision and text encoders are loaded
+    via the [`~AutoModel.from_pretrained`] method. The projection layers are automatically added to the model and
+    should be fine-tuned on a downstream task, like contrastive image-text modeling.
+
+    In [LiT: Zero-Shot Transfer with Locked-image Text Tuning](https://arxiv.org/abs/2111.07991) it is shown how
+    leveraging pre-trained (locked/frozen) image and text model for contrastive learning yields significant improvment
+    on new zero-shot vision tasks such as image classification or retrieval.
+
+    After such a Vision-Text-Dual-Encoder model has been trained/fine-tuned, it can be saved/loaded just like any other
+    models (see the examples for more information).
+
+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass.
+    Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
+    and behavior.
+
+    Parameters:
+        config ([`VisionEncoderDecoderConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+class VisualBertConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`VisualBertModel`]. It is used to instantiate an
+    VisualBERT model according to the specified arguments, defining the model architecture. Instantiating a
+    configuration with the defaults will yield a similar configuration to that of the VisualBERT
+    [uclanlp/visualbert-vqa-coco-pre](https://huggingface.co/uclanlp/visualbert-vqa-coco-pre) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 30522):
+            Vocabulary size of the VisualBERT model. Defines the number of different tokens that can be represented by
+            the `inputs_ids` passed when calling [`VisualBertModel`]. Vocabulary size of the model. Defines the
+            different tokens that can be represented by the `inputs_ids` passed to the forward method of
+            [`VisualBertModel`].
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimensionality of the encoder layers and the pooler layer.
+        visual_embedding_dim (`int`, *optional*, defaults to 512):
+            Dimensionality of the visual embeddings to be passed to the model.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        intermediate_size (`int`, *optional*, defaults to 3072):
+            Dimensionality of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"selu"` and `"gelu_new"` are supported.
+        hidden_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout ratio for the attention probabilities.
+        max_position_embeddings (`int`, *optional*, defaults to 512):
+            The maximum sequence length that this model might ever be used with. Typically set this to something large
+            just in case (e.g., 512 or 1024 or 2048).
+        type_vocab_size (`int`, *optional*, defaults to 2):
+            The vocabulary size of the `token_type_ids` passed when calling [`VisualBertModel`].
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-12):
+            The epsilon used by the layer normalization layers.
+        bypass_transformer (`bool`, *optional*, defaults to `False`):
+            Whether or not the model should bypass the transformer for the visual embeddings. If set to `True`, the
+            model directly concatenates the visual embeddings from [`VisualBertEmbeddings`] with text output from
+            transformers, and then pass it to a self-attention layer.
+        special_visual_initialize (`bool`, *optional*, defaults to `True`):
+            Whether or not the visual token type and position type embedding weights should be initialized the same as
+            the textual token type and positive type embeddings. When set to `True`, the weights of the textual token
+            type and position type embeddings are copied to the respective visual embedding layers.
+
+
+    Example:
+
+    ```python
+    >>> from transformers import VisualBertConfig, VisualBertModel
+
+    >>> # Initializing a VisualBERT visualbert-vqa-coco-pre style configuration
+    >>> configuration = VisualBertConfig.from_pretrained("uclanlp/visualbert-vqa-coco-pre")
+
+    >>> # Initializing a model (with random weights) from the visualbert-vqa-coco-pre style configuration

+class ViTConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`ViTModel`]. It is used to instantiate an ViT
+    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
+    defaults will yield a similar configuration to that of the ViT
+    [google/vit-base-patch16-224](https://huggingface.co/google/vit-base-patch16-224) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+
+    Args:
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimensionality of the encoder layers and the pooler layer.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        intermediate_size (`int`, *optional*, defaults to 3072):
+            Dimensionality of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"selu"` and `"gelu_new"` are supported.
+        hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-12):
+            The epsilon used by the layer normalization layers.
+        image_size (`int`, *optional*, defaults to 224):
+            The size (resolution) of each image.
+        patch_size (`int`, *optional*, defaults to 16):
+            The size (resolution) of each patch.
+        num_channels (`int`, *optional*, defaults to 3):
+            The number of input channels.
+        qkv_bias (`bool`, *optional*, defaults to `True`):
+            Whether to add a bias to the queries, keys and values.
+        encoder_stride (`int`, *optional*, defaults to 16):
+           Factor to increase the spatial resolution by in the decoder head for masked image modeling.

+
+    This model inherits from [`FlaxPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading, saving and converting weights from PyTorch models)
+
+    This model is also a
+    [flax.linen.Module](https://flax.readthedocs.io/en/latest/api_reference/flax.linen/module.html) subclass. Use it as
+    a regular Flax linen Module and refer to the Flax documentation for all matter related to general usage and
+    behavior.
+
+    Finally, this model supports inherent JAX features such as:
+
+    - [Just-In-Time (JIT) compilation](https://jax.readthedocs.io/en/latest/jax.html#just-in-time-compilation-jit)
+    - [Automatic Differentiation](https://jax.readthedocs.io/en/latest/jax.html#automatic-differentiation)
+    - [Vectorization](https://jax.readthedocs.io/en/latest/jax.html#vectorization-vmap)
+    - [Parallelization](https://jax.readthedocs.io/en/latest/jax.html#parallelization-pmap)
+
+    Parameters:
+        config ([`ViTConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~FlaxPreTrainedModel.from_pretrained`] method to load the model weights.
+        dtype (`jax.numpy.dtype`, *optional*, defaults to `jax.numpy.float32`):
+            The data type of the computation. Can be one of `jax.numpy.float32`, `jax.numpy.float16` (on GPUs) and
+            `jax.numpy.bfloat16` (on TPUs).
+
+            This can be used to enable mixed-precision training or half-precision inference on GPUs or TPUs. If
+            specified all the computation will be performed with the given `dtype`.
+
+            **Note that this only specifies the dtype of the computation and does not influence the dtype of model
+            parameters.**
+
+            If you wish to change the dtype of the model parameters, see [`~FlaxPreTrainedModel.to_fp16`] and
+            [`~FlaxPreTrainedModel.to_bf16`].

+        pixel_values (`numpy.ndarray` of shape `(batch_size, num_channels, height, width)`):
+            Pixel values. Pixel values can be obtained using [`AutoImageProcessor`]. See [`ViTImageProcessor.__call__`]
+            for details.
+
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail.

+    This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it
+    as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and
+    behavior.
+
+    <Tip>
+
+    TensorFlow models and layers in `transformers` accept two formats as input:
+
+    - having all inputs as keyword arguments (like PyTorch models), or
+    - having all inputs as a list, tuple or dict in the first positional argument.
+
+    The reason the second format is supported is that Keras methods prefer this format when passing inputs to models
+    and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just
+    pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second
+    format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with
+    the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first
+    positional argument:
+
+    - a single Tensor with `pixel_values` only and nothing else: `model(pixel_values)`
+    - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
+    `model([pixel_values, attention_mask])` or `model([pixel_values, attention_mask, token_type_ids])`
+    - a dictionary with one or several input Tensors associated to the input names given in the docstring:
+    `model({"pixel_values": pixel_values, "token_type_ids": token_type_ids})`
+
+    Note that when creating models and layers with
+    [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry
+    about any of this, as you can just pass inputs like you would to any other Python function!

+    This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it

+
+    <Tip>
+
+    TensorFlow models and layers in `transformers` accept two formats as input:
+
+    - having all inputs as keyword arguments (like PyTorch models), or
+    - having all inputs as a list, tuple or dict in the first positional argument.
+
+    The reason the second format is supported is that Keras methods prefer this format when passing inputs to models
+    and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just
+    pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second
+    format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with
+    the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first
+    positional argument:
+
+    - a single Tensor with `pixel_values` only and nothing else: `model(pixel_values)`
+    - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
+    `model([pixel_values, attention_mask])` or `model([pixel_values, attention_mask, token_type_ids])`
+    - a dictionary with one or several input Tensors associated to the input names given in the docstring:
+    `model({"pixel_values": pixel_values, "token_type_ids": token_type_ids})`
+
+    Note that when creating models and layers with
+    [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry
+    about any of this, as you can just pass inputs like you would to any other Python function!

+    the defaults will yield a similar configuration to that of the ViT
+    [facebook/vit_msn_base](https://huggingface.co/facebook/vit_msn_base) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.

+            `"relu"`, `"selu"` and `"gelu_new"` are supported.
+        hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-06):
+            The epsilon used by the layer normalization layers.
+        image_size (`int`, *optional*, defaults to 224):
+            The size (resolution) of each image.
+        patch_size (`int`, *optional*, defaults to 16):
+            The size (resolution) of each patch.

+    r"""
+    This is the configuration class to store the configuration of a [`VitDetModel`]. It is used to instantiate an
+    VitDet model according to the specified arguments, defining the model architecture. Instantiating a configuration
+    with the defaults will yield a similar configuration to that of the VitDet
+    [google/vitdet-base-patch16-224](https://huggingface.co/google/vitdet-base-patch16-224) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimensionality of the encoder layers and the pooler layer.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        mlp_ratio (`int`, *optional*, defaults to 4):
+            Ratio of mlp hidden dim to embedding dim.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"selu"` and `"gelu_new"` are supported.
+        dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-06):
+            The epsilon used by the layer normalization layers.
+        image_size (`int`, *optional*, defaults to 224):
+            The size (resolution) of each image.
+        pretrain_image_size (`int`, *optional*, defaults to 224):
+            The size (resolution) of each image during pretraining.
+        patch_size (`int`, *optional*, defaults to 16):
+            The size (resolution) of each patch.
+        num_channels (`int`, *optional*, defaults to 3):
+            The number of input channels.
+        qkv_bias (`bool`, *optional*, defaults to `True`):
+            Whether to add a bias to the queries, keys and values.
+        drop_path_rate (`float`, *optional*, defaults to 0.0):
+            Stochastic depth rate.
+        window_block_indices (`List[int]`, *optional*, defaults to `[]`):
+            List of indices of blocks that should have window attention instead of regular global self-attention.
+        residual_block_indices (`List[int]`, *optional*, defaults to `[]`):
+            List of indices of blocks that should have an extra residual block after the MLP.
+        use_absolute_position_embeddings (`bool`, *optional*, defaults to `True`):
+            Whether to add absolute position embeddings to the patch embeddings.
+        use_relative_position_embeddings (`bool`, *optional*, defaults to `False`):
+            Whether to add relative position embeddings to the attention maps.
+        window_size (`int`, *optional*, defaults to 0):
+            The size of the attention window.
+        out_features (`List[str]`, *optional*):
+            If used as backbone, list of features to output. Can be any of `"stem"`, `"stage1"`, `"stage2"`, etc.
+            (depending on how many stages the model has). If unset and `out_indices` is set, will default to the
+            corresponding stages. If unset and `out_indices` is unset, will default to the last stage. Must be in the
+            same order as defined in the `stage_names` attribute.
+        out_indices (`List[int]`, *optional*):
+            If used as backbone, list of indices of features to output. Can be any of 0, 1, 2, etc. (depending on how
+            many stages the model has). If unset and `out_features` is set, will default to the corresponding stages.
+            If unset and `out_features` is unset, will default to the last stage. Must be in the

+class VitMatteConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of [`VitMatteForImageMatting`]. It is used to
+    instantiate a ViTMatte model according to the specified arguments, defining the model architecture. Instantiating a
+    configuration with the defaults will yield a similar configuration to that of the ViTMatte
+    [hustvl/vitmatte-small-composition-1k](https://huggingface.co/hustvl/vitmatte-small-composition-1k) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        backbone_config (`PretrainedConfig` or `dict`, *optional*, defaults to `VitDetConfig()`):
+            The configuration of the backbone model.
+        backbone (`str`, *optional*):
+            Name of backbone to use when `backbone_config` is `None`. If `use_pretrained_backbone` is `True`, this
+            will load the corresponding pretrained weights from the timm or transformers library. If `use_pretrained_backbone`
+            is `False`, this loads the backbone's config and uses that to initialize the backbone with random weights.
+        use_pretrained_backbone (`bool`, *optional*, defaults to `False`):
+            Whether to use pretrained weights for the backbone.
+        use_timm_backbone (`bool`, *optional*, defaults to `False`):
+            Whether to load `backbone` from the timm library. If `False`, the backbone is loaded from the transformers
+            library.
+        backbone_kwargs (`dict`, *optional*):
+            Keyword arguments to be passed to AutoBackbone when loading from a checkpoint
+            e.g. `{'out_indices': (0, 1, 2, 3)}`. Cannot be specified if `backbone_config` is set.
+        hidden_size (`int`, *optional*, defaults to 384):
+            The number of input channels of the decoder.
+        batch_norm_eps (`float`, *optional*, defaults to 1e-05):
+            The epsilon used by the batch norm layers.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        convstream_hidden_sizes (`List[int]`, *optional*, defaults to `[48, 96, 192]`):
+            The output channels of the ConvStream module.
+        fusion_hidden_sizes (`List[int]`, *optional*, defaults to `[256, 128, 64, 32]`):
+            The output channels of the Fusion blocks.
+
+    Example:
+
+    ```python
+    >>> from transformers import VitMatteConfig, VitMatteForImageMatting
+
+    >>> # Initializing a ViTMatte hustvl/vitmatte-small-composition-1k style configuration
+    >>> configuration = VitMatteConfig()

+    r"""
+    This is the configuration class to store the configuration of a [`VitPoseForPoseEstimation`]. It is used to instantiate a
+    VitPose model according to the specified arguments, defining the model architecture. Instantiating a configuration
+    with the defaults will yield a similar configuration to that of the VitPose
+    [usyd-community/vitpose-base-simple](https://huggingface.co/usyd-community/vitpose-base-simple) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        backbone_config (`PretrainedConfig` or `dict`, *optional*, defaults to `VitPoseBackboneConfig()`):
+            The configuration of the backbone model. Currently, only `backbone_config` with `vitpose_backbone` as `model_type` is supported.
+        backbone (`str`, *optional*):
+            Name of backbone to use when `backbone_config` is `None`. If `use_pretrained_backbone` is `True`, this
+            will load the corresponding pretrained weights from the timm or transformers library. If `use_pretrained_backbone`
+            is `False`, this loads the backbone's config and uses that to initialize the backbone with random weights.
+        use_pretrained_backbone (`bool`, *optional*, defaults to `False`):
+            Whether to use pretrained weights for the backbone.
+        use_timm_backbone (`bool`, *optional*, defaults to `False`):
+            Whether to load `backbone` from the timm library. If `False`, the backbone is loaded from the transformers
+            library.
+        backbone_kwargs (`dict`, *optional*):
+            Keyword arguments to be passed to AutoBackbone when loading from a checkpoint
+            e.g. `{'out_indices': (0, 1, 2, 3)}`. Cannot be specified if `backbone_config` is set.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        scale_factor (`int`, *optional*, defaults to 4):
+            Factor to upscale the feature maps coming from the ViT backbone.
+        use_simple_decoder (`bool`, *optional*, defaults to `True`):
+            Whether to use a `VitPoseSimpleDecoder` to decode the feature maps from the backbone into heatmaps. Otherwise it uses `VitPoseClassicDecoder`.
+
+
+    Example:
+
+    ```python
+    >>> from transformers import VitPoseConfig, VitPoseForPoseEstimation
+
+    >>> # Initializing a VitPose configuration
+    >>> configuration = VitPoseConfig()
+
+    >>> # Initializing a model (with random weights) from the configuration

+    r"""
+    This is the configuration class to store the configuration of a [`VitPoseBackbone`]. It is used to instantiate a
+    VitPose model according to the specified arguments, defining the model architecture. Instantiating a configuration
+    with the defaults will yield a similar configuration to that of the VitPose
+    [usyd-community/vitpose-base-simple](https://huggingface.co/usyd-community/vitpose-base-simple) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        image_size (`int`, *optional*, defaults to `[256, 192]`):
+            The size (resolution) of each image.
+        patch_size (`List[int]`, *optional*, defaults to `[16, 16]`):
+            The size (resolution) of each patch.
+        num_channels (`int`, *optional*, defaults to 3):
+            The number of input channels.
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimensionality of the encoder layers and the pooler layer.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        mlp_ratio (`int`, *optional*, defaults to 4):
+            The ratio of the hidden size in the feedforward network to the hidden size in the attention layers.
+        num_experts (`int`, *optional*, defaults to 1):
+            The number of experts in the MoE layer.
+        part_features (`int`, *optional*):
+            The number of part features to output. Only used in case `num_experts` is greater than 1.
+        hidden_act (`str`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"selu"` and `"gelu_new"` are supported.
+        hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout probabilitiy for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-12):
+            The epsilon used by the layer normalization layers.
+        qkv_bias (`bool`, *optional*, defaults to `True`):
+            Whether to add a bias to the queries, keys and values.
+        out_features (`List[str]`, *optional*):
+            If used as backbone, list of features to output. Can be any of `"stem"`, `"stage1"`, `"stage2"`, etc.
+            (depending on how many stages the model has). If unset and `out_indices` is set, will default to the
+            corresponding stages. If unset and `out_indices` is unset, will default to the last stage. Must be in the
+            same order as defined in the `stage_names` attribute.
+        out_indices (`List[int]`, *optional*):
+            If used as backbone, list of indices of features to output. Can be any of 0, 1, 2, etc. (depending on how
+            many stages the model has). If unset and `out_features` is set, will default to the corresponding stages.
+            If unset and `out_features` is unset, will default to the last stage. Must be in the
+            same order as defined in the `stage_names` attribute.

+class VivitConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`VivitModel`]. It is used to instantiate a ViViT
+    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
+    defaults will yield a similar configuration to that of the ViViT
+    [google/vivit-b-16x2-kinetics400](https://huggingface.co/google/vivit-b-16x2-kinetics400) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        image_size (`int`, *optional*, defaults to 224):
+            The size (resolution) of each image.
+        num_frames (`int`, *optional*, defaults to 32):
+            The number of frames in each video.
+        tubelet_size (`List[int]`, *optional*, defaults to `[2, 16, 16]`):
+            The size (resolution) of each tubelet.
+        num_channels (`int`, *optional*, defaults to 3):
+            The number of input channels.
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimensionality of the encoder layers and the pooler layer.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        intermediate_size (`int`, *optional*, defaults to 3072):
+            Dimensionality of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu_fast"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"selu"`, `"gelu_fast"` and `"gelu_new"` are supported.
+        hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-06):
+            The epsilon used by the layer normalization layers.
+        qkv_bias (`bool`, *optional*, defaults to `True`):
+            Whether to add a bias to the queries, keys and values.
+
+    Example:
+
+    ```python
+    >>> from transformers import VivitConfig, VivitModel
+
+    >>> # Initializing a ViViT google/vivit-b-16x2-kinetics400 style configuration
+    >>> configuration = VivitConfig()

+    Representations](https://arxiv.org/abs/2006.11477) by Alexei Baevski, Henry Zhou, Abdelrahman Mohamed, Michael
+    Auli.
+
+    This model inherits from [`FlaxPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a Flax Linen
+    [flax.nn.Module](https://flax.readthedocs.io/en/latest/_autosummary/flax.nn.module.html) subclass. Use it as a
+    regular Flax Module and refer to the Flax documentation for all matter related to general usage and behavior.
+
+    Finally, this model supports inherent JAX features such as:
+
+    - [Just-In-Time (JIT) compilation](https://jax.readthedocs.io/en/latest/jax.html#just-in-time-compilation-jit)
+    - [Automatic Differentiation](https://jax.readthedocs.io/en/latest/jax.html#automatic-differentiation)

+    - [Parallelization](https://jax.readthedocs.io/en/latest/jax.html#parallelization-pmap)
+
+    Parameters:
+        config ([`Wav2Vec2Config`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~FlaxPreTrainedModel.from_pretrained`] method to load the model weights.
+        dtype (`jax.numpy.dtype`, *optional*, defaults to `jax.numpy.float32`):
+            The data type of the computation. Can be one of `jax.numpy.float32`, `jax.numpy.float16` (on GPUs) and
+            `jax.numpy.bfloat16` (on TPUs).
+
+            This can be used to enable mixed-precision training or half-precision inference on GPUs or TPUs. If
+            specified all the computation will be performed with the given `dtype`.
+
+            **Note that this only specifies the dtype of the computation and does not influence the dtype of model
+            parameters.**
+
+            If you wish to change the dtype of the model parameters, see [`~FlaxPreTrainedModel.to_fp16`] and

+    This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it
+    as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and
+    behavior.
+
+    <Tip>
+
+    TensorFlow models and layers in `transformers` accept two formats as input:
+
+    - having all inputs as keyword arguments (like PyTorch models), or
+    - having all inputs as a list, tuple or dict in the first positional argument.
+
+    The reason the second format is supported is that Keras methods prefer this format when passing inputs to models
+    and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just
+    pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second
+    format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with
+    the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first
+    positional argument:
+
+    - a single Tensor with `input_values` only and nothing else: `model(input_values)`
+    - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
+    `model([input_values, attention_mask])` or `model([input_values, attention_mask, token_type_ids])`
+    - a dictionary with one or several input Tensors associated to the input names given in the docstring:
+    `model({"input_values": input_values, "token_type_ids": token_type_ids})`
+
+    Note that when creating models and layers with
+    [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry
+    about any of this, as you can just pass inputs like you would to any other Python function!

+            cache_dir (`Union[str, os.PathLike]`, *optional*):
+                Path to a directory in which a downloaded pretrained model configuration should be cached if the

+            force_download (`bool`, *optional*, defaults to `False`):
+                Whether or not to force the (re-)download of the model weights and configuration files, overriding the

+            resume_download:
+                Deprecated and ignored. All downloads are now resumed by default when possible.
+                Will be removed in v5 of Transformers.
+            proxies (`Dict[str, str]`, *optional*):
+                A dictionary of proxy servers to use by protocol or endpoint, e.g., `{'http': 'foo.bar:3128',
+                'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request.

+                Whether or not to only look at local files (i.e., do not try to download the model).
+            token (`str` or `bool`, *optional*):
+                The token to use as HTTP bearer authorization for remote files. If `True`, or not specified, will use

+    Auli.
+
+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving etc.).
+
+    This model is a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) sub-class. Use
+    it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage and
+    behavior.
+
+    Parameters:
+        config ([`Wav2Vec2Config`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the

+            into an array of type `List[float]` or a `numpy.ndarray`, *e.g.* via the soundfile library (`pip install
+            soundfile`). To prepare the array into `input_values`, the [`AutoProcessor`] should be used for padding and
+            conversion into a tensor of type `torch.FloatTensor`. See [`Wav2Vec2Processor.__call__`] for details.
+        attention_mask (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Mask to avoid performing convolution and attention on padding token indices. Mask values selected in `[0,

+                  sequence if provided).
+                - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum
+                  acceptable input length for the model if that argument is not provided.
+                - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different
+                  lengths).
+            max_length (`int`, *optional*):
+                Controls the maximum length to use by one of the truncation/padding parameters.
+

+                is required by one of the truncation/padding parameters. If the model has no specific maximum input
+                length (like XLNet) truncation/padding to a maximum length will be deactivated.
+            pad_to_multiple_of (`int`, *optional*):
+                If set will pad the sequence to a multiple of the provided value. This is especially useful to enable
+                the use of Tensor Cores on NVIDIA hardware with compute capability `>= 7.5` (Volta).
+            return_tensors (`str` or [`~utils.TensorType`], *optional*):
+                If set, will return tensors instead of list of python integers. Acceptable values are:
+
+                - `'tf'`: Return TensorFlow `tf.constant` objects.
+                - `'pt'`: Return PyTorch `torch.Tensor` objects.
+                - `'np'`: Return Numpy `np.ndarray` objects.
+            verbose (`bool`, *optional*, defaults to `True`):

+    Auli.
+
+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving etc.).
+
+    This model is a PyTorch [nn.Module](https://pytorch.org/docs/stable/nn.html#nn.Module) sub-class. Use it as a
+    regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage and behavior.
+
+    Parameters:
+        config ([`Wav2Vec2BertConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the

+    Representations](https://arxiv.org/abs/2006.11477) by Alexei Baevski, Henry Zhou, Abdelrahman Mohamed, Michael
+    Auli.
+
+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving etc.).
+
+    This model is a PyTorch [nn.Module](https://pytorch.org/docs/stable/nn.html#nn.Module) sub-class. Use it as a
+    regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage and behavior.
+
+    Parameters:
+        config ([`Wav2Vec2ConformerConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+    Args:
+        input_values (`torch.FloatTensor` of shape `(batch_size, sequence_length)`):
+            Float values of input raw speech waveform. Values can be obtained by loading a `.flac` or `.wav` audio file
+            into an array of type `List[float]` or a `numpy.ndarray`, *e.g.* via the soundfile library (`pip install
+            soundfile`). To prepare the array into `input_values`, the [`AutoProcessor`] should be used for padding and
+            conversion into a tensor of type `torch.FloatTensor`. See [`Wav2Vec2Processor.__call__`] for details.
+        attention_mask (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Mask to avoid performing convolution and attention on padding token indices. Mask values selected in `[0,
+            1]`:
+
+            - 1 for tokens that are **not masked**,
+            - 0 for tokens that are **masked**.
+
+            [What are attention masks?](../glossary#attention-mask)
+
+            <Tip warning={true}>
+
+            `attention_mask` should only be passed if the corresponding processor has `config.return_attention_mask ==
+            True`. For all models whose processor has `config.return_attention_mask == False`, such as
+            [wav2vec2-conformer-rel-pos-large](https://huggingface.co/facebook/wav2vec2-conformer-rel-pos-large),
+            `attention_mask` should **not** be passed to avoid degraded performance when doing batched inference. For
+            such models `input_values` should simply be padded with 0 and passed without `attention_mask`. Be aware
+            that these models also yield slightly different results depending on whether `input_values` is padded or
+            not.
+
+            </Tip>
+
+        output_attentions (`bool`, *optional*):

+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail.
+        return_dict (`bool`, *optional*):

+    WavLM was proposed in [WavLM: Unified Speech Representation Learning with Labeled and Unlabeled
+    Data](https://arxiv.org/abs/2110.13900) by Sanyuan Chen, Chengyi Wang, Zhengyang Chen, Yu Wu, Shujie Liu, Zhuo
+    Chen, Jinyu Li, Naoyuki Kanda, Takuya Yoshioka, Xiong Xiao, Jian Wu, Long Zhou, Shuo Ren, Yanmin Qian, Yao Qian,
+    Jian Wu, Michael Zeng, Xiangzhan Yu, Furu Wei.
+
+    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving etc.).
+
+    This model is a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) sub-class. Use
+    it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage and
+    behavior.
+
+    Parameters:
+        config ([`WavLMConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+WAVLM_INPUTS_DOCSTRING = r"""
+    Args:
+        input_values (`torch.FloatTensor` of shape `(batch_size, sequence_length)`):
+            Float values of input raw speech waveform. Values can be obtained by loading a `.flac` or `.wav` audio file
+            into an array of type `List[float]` or a `numpy.ndarray`, *e.g.* via the soundfile library (`pip install
+            soundfile`). To prepare the array into `input_values`, the [`AutoProcessor`] should be used for padding and
+            conversion into a tensor of type `torch.FloatTensor`. See [`Wav2Vec2Processor.__call__`] for details.
+        attention_mask (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Mask to avoid performing convolution and attention on padding token indices. Mask values selected in `[0,
+            1]`:
+
+            - 1 for tokens that are **not masked**,
+            - 0 for tokens that are **masked**.
+
+            [What are attention masks?](../glossary#attention-mask)
+
+            <Tip warning={true}>
+
+            `attention_mask` should only be passed if the corresponding processor has `config.return_attention_mask ==
+            True`. For all models whose processor has `config.return_attention_mask == False`, `attention_mask` should
+            **not** be passed to avoid degraded performance when doing batched inference. For such models
+            `input_values` should simply be padded with 0 and passed without `attention_mask`. Be aware that these
+            models also yield slightly different results depending on whether `input_values` is padded or not.
+
+            </Tip>
+
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail.
+        return_dict (`bool`, *optional*):
+            Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.

+class WhisperConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`WhisperModel`]. It is used to instantiate a
+    Whisper model according to the specified arguments, defining the model architecture. Instantiating a configuration
+    with the defaults will yield a similar configuration to that of the Whisper
+    [openai/whisper-tiny](https://huggingface.co/openai/whisper-tiny) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 51865):
+            Vocabulary size of the Whisper model. Defines the number of different tokens that can be represented by the

+            The maximum sequence length of log-mel filter-bank features that this model might ever be used with.
+        max_target_positions (`int`, *optional*, defaults to 448):
+            The maximum sequence length that this model might ever be used with. Typically set this to something large
+            just in case (e.g., 512 or 1024 or 2048).
+        pad_token_id (`int`, *optional*, defaults to 50256):
+            Padding token id.

+        suppress_tokens (`List[int]`, *optional*):
+            A list containing the non-speech tokens that will be used by the logit processor in the `generate`
+            function. NON_SPEECH_TOKENS and NON_SPEECH_TOKENS_MULTI each correspond to the `english-only` and the

+            Recognition](https://arxiv.org/abs/1904.08779).
+        mask_time_prob (`float`, *optional*, defaults to 0.05):
+            Percentage (between 0 and 1) of all feature vectors along the time axis which will be masked. The masking

+            mask_time_min_masks''
+        mask_feature_prob (`float`, *optional*, defaults to 0.0):
+            Percentage (between 0 and 1) of all feature vectors along the feature axis which will be masked. The
+            masking procecure generates `mask_feature_prob*len(feature_axis)/mask_time_length` independent masks over
+            the axis. If reasoning from the propability of each feature vector to be chosen as the start of the vector
+            span to be masked, *mask_feature_prob* should be `prob_vector_start*mask_feature_length`. Note that overlap
+            may decrease the actual percentage of masked vectors. This is only relevant if `apply_spec_augment is
+            True`.
+        mask_feature_length (`int`, *optional*, defaults to 10):
+            Length of vector span along the feature axis.
+        mask_feature_min_masks (`int`, *optional*, defaults to 0),:

+        median_filter_width (`int`, *optional*, defaults to 7):
+            Width of the median filter used to smoothen to cross-attention outputs when computing token timestamps.

+    Example:
+
+    ```python
+    >>> from transformers import WhisperConfig, WhisperModel
+
+    >>> # Initializing a Whisper tiny style configuration
+    >>> configuration = WhisperConfig()

+    Constructs a Whisper feature extractor.
+
+    This feature extractor inherits from [`~feature_extraction_sequence_utils.SequenceFeatureExtractor`] which contains
+    most of the main methods. Users should refer to this superclass for more information regarding those methods.
+
+    This class extracts mel-filter bank features from raw speech using a custom numpy implementation of the `Short Time
+    Fourier Transform` which should match pytorch's `torch.stft` equivalent.
+
+    Args:
+        feature_size (`int`, *optional*, defaults to 80):
+            The feature dimension of the extracted features.
+        sampling_rate (`int`, *optional*, defaults to 16000):
+            The sampling rate at which the audio files should be digitalized expressed in hertz (Hz).
+        hop_length (`int`, *optional*, defaults to 160):
+            Length of the overlaping windows for the STFT used to obtain the Mel Frequency coefficients.
+        chunk_length (`int`, *optional*, defaults to 30):
+            The maximum number of chuncks of `sampling_rate` samples used to trim and pad longer or shorter audio
+            sequences.
+        n_fft (`int`, *optional*, defaults to 400):
+            Size of the Fourier transform.
+        padding_value (`float`, *optional*, defaults to 0.0):
+            Padding value used to pad the audio. Should correspond to silences.
+        dither (`float`, *optional*, defaults to 0.0):
+            Adds dithering. In other words, adds a small Gaussian noise to each frame.
+            E.g. use 0.0001 to add dithering with a normal distribution centered
+            around 0.0 with standard deviation 0.0001 (assuming [-1,+1] range of raw_speech).
+            The value 0.0 means no dithering.
+            Dithering has similar effect as `spectrogram(mel_floor=...)`. It reduces
+            the high log_mel_fbank values for signals with hard-zero sections,
+            when VAD cutoff is present in the signal.

+
+        Args:
+            raw_speech (`np.ndarray`, `List[float]`, `List[np.ndarray]`, `List[List[float]]`):
+                The sequence or batch of sequences to be padded. Each sequence can be a numpy array, a list of float
+                values, a list of numpy arrays or a list of list of float values. Must be mono channel audio, not
+                stereo, i.e. single float per timestep.
+            truncation (`bool`, *optional*, default to `True`):
+                Activates truncation to cut input sequences longer than *max_length* to *max_length*.
+            pad_to_multiple_of (`int`, *optional*, defaults to None):
+                If set will pad the sequence to a multiple of the provided value.
+
+                This is especially useful to enable the use of Tensor Cores on NVIDIA hardware with compute capability
+                `>= 7.5` (Volta), or on TPUs which benefit from having sequence lengths be a multiple of 128.
+            return_attention_mask (`bool`, *optional*):
+                Whether to return the attention mask. If left to the default, will return the attention mask according
+                to the specific feature_extractor's default.
+
+                [What are attention masks?](../glossary#attention-mask)
+
+                <Tip>
+
+                For Whisper models, `attention_mask` should always be passed for batched inference, to avoid subtle
+                bugs.
+
+                </Tip>
+
+            return_tensors (`str` or [`~utils.TensorType`], *optional*):
+                If set, will return tensors instead of list of python integers. Acceptable values are:
+
+                - `'tf'`: Return TensorFlow `tf.constant` objects.
+                - `'pt'`: Return PyTorch `torch.Tensor` objects.
+                - `'np'`: Return Numpy `np.ndarray` objects.
+            sampling_rate (`int`, *optional*):
+                The sampling rate at which the `raw_speech` input was sampled. It is strongly recommended to pass
+                `sampling_rate` at the forward call to prevent silent errors and allow automatic speech recognition
+                pipeline.
+            padding_value (`float`, *optional*, defaults to 0.0):
+                The value that is used to fill the padding values / vectors.
+            do_normalize (`bool`, *optional*, defaults to `False`):
+                Whether or not to zero-mean unit-variance normalize the input. Normalizing can help to significantly
+                improve the performance of the model.
+            device (`str`, *optional*, defaults to `'cpu'`):
+                Specifies the device for computation of the log-mel spectrogram of audio signals in the
+                `_torch_extract_fbank_features` method. (e.g., "cpu", "cuda")
+            return_token_timestamps (`bool`, *optional*, defaults to `None`):
+                Whether or not to return the number of frames of the input raw_speech.
+                These num_frames can be used by the model to compute word level timestamps.

+
+        Most generation-controlling parameters are set in `generation_config` which, if not passed, will be set to the
+        model's default generation configuration. You can override any `generation_config` by passing the corresponding
+        parameters to generate(), e.g. `.generate(inputs, num_beams=4, do_sample=True)`.
+
+        For an overview of generation strategies and code examples, check out the [following
+        guide](./generation_strategies).
+
+        </Tip>
+
+        Parameters:
+            input_features (`torch.Tensor` of shape `(batch_size, feature_size, sequence_length)`, *optional*):
+                Float values of log-mel features extracted from the raw speech waveform. The raw speech waveform can be obtained by
+                loading a `.flac` or `.wav` audio file into an array of type `List[float]` or a `numpy.ndarray`, *e.g.* via
+                the soundfile library (`pip install soundfile`). To prepare the array into `input_features`, the
+                [`AutoFeatureExtractor`] should be used for extracting the mel features, padding and conversion into a
+                tensor of type `torch.FloatTensor`. See [`~WhisperFeatureExtractor.__call__`] for details.
+            generation_config ([`~generation.GenerationConfig`], *optional*):
+                The generation configuration to be used as base parametrization for the generation call. `**kwargs`
+                passed to generate matching the attributes of `generation_config` will override them. If
+                `generation_config` is not provided, the default will be used, which had the following loading
+                priority: 1) from the `generation_config.json` model file, if it exists; 2) from the model
+                configuration. Please note that unspecified parameters will inherit [`~generation.GenerationConfig`]'s
+                default values, whose documentation should be checked to parameterize generation.
+            logits_processor (`LogitsProcessorList`, *optional*):
+                Custom logits processors that complement the default logits processors built from arguments and
+                generation config. If a logit processor is passed that is already created with the arguments or a
+                generation config an error is thrown. This feature is intended for advanced users.
+            stopping_criteria (`StoppingCriteriaList`, *optional*):
+                Custom stopping criteria that complement the default stopping criteria built from arguments and a
+                generation config. If a stopping criteria is passed that is already created with the arguments or a
+                generation config an error is thrown. This feature is intended for advanced users.
+            prefix_allowed_tokens_fn (`Callable[[int, torch.Tensor], List[int]]`, *optional*):
+                If provided, this function constraints the beam search to allowed tokens only at each step. If not
+                provided no constraint is applied. This function takes 2 arguments: the batch ID `batch_id` and
+                `input_ids`. It has to return a list with the allowed tokens for the next generation step conditioned
+                on the batch ID `batch_id` and the previously generated tokens `inputs_ids`. This argument is useful
+                for constrained generation conditioned on the prefix, as described in [Autoregressive Entity
+                Retrieval](https://arxiv.org/abs/2010.00904).
+            synced_gpus (`bool`, *optional*, defaults to `False`):
+                Whether to continue running the while loop until max_length (needed to avoid deadlocking with
+                `FullyShardedDataParallel` and DeepSpeed ZeRO Stage 3).
+            return_timestamps (`bool`, *optional*):
+                Whether to return the timestamps with the text. This enables the `WhisperTimestampsLogitsProcessor`.
+            task (`str`, *optional*):
+                Task to use for generation, either "translate" or "transcribe". The `model.config.forced_decoder_ids`
+                will be updated accordingly.
+            language (`str` or list of `str`, *optional*):
+                Language token to use for generation, can be either in the form of `<|en|>`, `en` or `english`. For
+                batched generation, a list of language tokens can be passed. You can find all the possible language
+                tokens in the `model.generation_config.lang_to_id` dictionary.
+            is_multilingual (`bool`, *optional*):
+                Whether or not the model is multilingual.
+            prompt_ids (`torch.Tensor`, *optional*):
+                Rank-1 tensor of token IDs created by passing text to [`~WhisperProcessor.get_prompt_ids`] that is
+                provided as a prompt to each chunk. This can be used to provide or "prompt-engineer" a context for
+                transcription, e.g. custom vocabularies or proper nouns to make it more likely to predict those words
+                correctly. It cannot be used in conjunction with `decoder_start_token_id` as it overwrites this value.
+            prompt_condition_type (`str`, *optional*):
+                Only relevant for long-form transcription. Condition type of `prompt_ids`. 'first-segment' means only the first segment is conditioned on `prompt_ids`. 'all-segments' means each segment is conditioned on `prompt_ids`. Make sure to enable `condition_on_prev_tokens` for 'all-segments'.
+                Defaults to 'first-segment'. For short-term transcription only 'first-segment' is possible.
+            condition_on_prev_tokens (`bool`, *optional*):
+                Only relevant for long-form transcription. Whether to condition each segment on the previous segment.
+                As shown in the [the Whisper paper](https://cdn.openai.com/papers/whisper.pdf), this can help to improve
+                performance.
+            temperature (`float` or list of `float`, *optional*):
+                The temperature to be used for generation. Passing a single `float` value and `do_sample=True` activates
+                generation using sampling. For long-form transcription, temperature fallback can be activated by passing
+                a list of float values such as (0.0, 0.2, 0.4, 0.6, 0.8, 1.0). As shown in the [the Whisper paper](https://cdn.openai.com/papers/whisper.pdf), this can help to improve
+                performance.
+            compression_ratio_threshold (`float`, *optional*):
+                Only relevant for long-form transcription. If defined, the zlib compression rate of each segment will be computed. If the compression rate of
+                a segment is higher than `compression_ratio_threshold`, temperature fallback is activated: the generated segment is discarded and the generation is
+                repeated using a higher temperature. The intuition behind this feature is that segments with very high compression rates
+                suffer from a lot of repetition. The unwanted repetition can be reduced by injecting more randomness by increasing the temperature. If `compression_ratio_threshold` is defined
+                make sure that `temperature` is a list of values. A common value for `compression_ratio_threshold` is 1.35.
+                As shown in the [the Whisper paper](https://cdn.openai.com/papers/whisper.pdf), this can help to improve
+                performance.
+            logprob_threshold (`float`, *optional*):
+                Only relevant for long-form transcription. If defined, the average log-probability of each segment will be computed. If the log-probability of
+                a given segment is lower than `logprob_threshold`, temperature fallback is activated: the generated segment is discarded and the generation is
+                repeated using a higher temperature. The intuition behind this feature is that segments of low log-probability
+                can be improved by injecting more randomness by increasing the temperature. If `logprob_threshold` is defined
+                make sure that `temperature` is a list of values. A common value for `logprob_threshold` is -1.0.
+                As shown in the [the Whisper paper](https://cdn.openai.com/papers/whisper.pdf), this can help to improve
+                performance.
+            no_speech_threshold (`float`, *optional*):
+                Only relevant for long-form transcription. If defined, the "no-speech" token combined with the `logprob_threshold`
+                is used to determine whether a segment contains only silence. In this case, the transcription for this segment
+                is skipped.
+                As shown in the [the Whisper paper](https://cdn.openai.com/papers/whisper.pdf), this can help to improve
+                performance.
+            num_segment_frames (`int`, *optional*):
+                The number of frames a single segment is made of. If not defined, `num_segment_frames` defaults to the model's stride
+                times the maximum input length.
+            attention_mask (`torch.Tensor`, *optional*):
+                `attention_mask` needs to be passed when doing long-form transcription using a batch size > 1.
+            time_precision (`int`, *optional*, defaults to 0.02):
+                The duration of output token in seconds. *E.g.* 0.02 means that a generated token on average accounts
+                for 20 ms.
+            time_precision_features (`int`, *optional*, defaults to 0.01):
+                The duration represented by a feature frame in seconds.
+            return_token_timestamps (`bool`, *optional*):
+                Whether to return token-level timestamps with the text. This can be used with or without the
+                `return_timestamps` option. To get word-level timestamps, use the tokenizer to group the tokens into
+                words.
+            return_segments (`bool`, *optional*, defaults to `False`):
+                Whether to additionally return a list of all segments. Note that this option can only be enabled
+                when doing long-form transcription.
+            return_dict_in_generate (`bool`, *optional*, defaults to `False`):
+                Whether or not to return a [`~utils.ModelOutput`] instead of just returning the generated tokens.
+                Note that when doing long-form transcription, `return_dict_in_generate` can only be enabled when
+                `return_segments` is set True. In this case the generation outputs of each segment is added to each
+                segment.
+            force_unique_generate_call (`bool`, *optional*):
+                Whether to force a unique call to the underlying GenerationMixin's [`~generation.GenerationMixin.generate`] method. This is useful for assisted decoding and testing purposes to ensure
+                that only one call to [`~generation.GenerationMixin.generate`] is made and therefore decoder input token ids and eos token ids are returned.
+            kwargs (`Dict[str, Any]`, *optional*):
+                Ad hoc parametrization of `generate_config` and/or additional model-specific kwargs that will be
+                forwarded to the `forward` function of the model. If the model is an encoder-decoder model, encoder
+                specific kwargs should not be prefixed and decoder specific kwargs should be prefixed with *decoder_*.
+        Return:
+            [`~utils.ModelOutput`] or `Dict[str, Any]` or `torch.LongTensor`:
+
+                A:
+                - [`~utils.ModelOutput`] when `return_dict_in_generate=True` and (`return_timestamps=False` or `force_unique_generate_call=True`), including the decoder input ids and end of sequence id.
+                - `Dict[str, Any]` when (`return_dict_in_generate=True` and `return_timestamps=True`) or `return_segments=True` or `return_token_timestamps=True`.
+                - `torch.LongTensor` in all other cases, excluding the decoder input ids and end of sequence id.
+
+                The possible [`~utils.ModelOutput`] types are:
+                - [`~generation.GenerateEncoderDecoderOutput`]
+                - [`~generation.GenerateBeamEncoderDecoderOutput`]
+
+                `segments` is a list of lists (one list per batch element) of `segment`.
+                A `segment` is a dictionary with keys `start`, `end`, `tokens`, `idxs`, and `result`.
+                - `start`: the start timestamp of the segment.
+                - `end`: the end timestamp of the segment.
+                - `tokens`: the tokens of the segment, excluding the decoder input ids and end of sequence id.
+                - `idxs`: the start (included) and end (excluded) indices of the `tokens` of the segment in the underlying call to GenerationMixin's [`~generation.GenerationMixin.generate`] (present in `result`).
+                - `result`: the result of the underlying call to GenerationMixin's [`~generation.GenerationMixin.generate`].
+
+                When `return_timestamps=True`, `return_dict_in_generate=True` applies to each call of the underlying GenerationMixin's [`~generation.GenerationMixin.generate`], with outputs stored in `result` of each `segment`.
+
+        Example:
+
+        - *Longform transcription*: To transcribe or translate audios longer than 30 seconds, process the audio files without truncation and pass all mel features at once to generate. It is necessary to set `return_timestamps=True`.
+        Indeed, long-form transcription uses a sequential algorithm based on timestamps predictions, with heuristics like compression ratio threshold, log probability threshold and temperature fallback. This algorithm is described in the [the Whisper original paper](https://cdn.openai.com/papers/whisper.pdf), section *3.8. Long-form Transcription*.

+        ```python
+        >>> import torch
+        >>> from transformers import AutoProcessor, WhisperForConditionalGeneration
+        >>> from datasets import load_dataset, Audio
+
+        >>> processor = AutoProcessor.from_pretrained("openai/whisper-tiny.en")
+        >>> model = WhisperForConditionalGeneration.from_pretrained("openai/whisper-tiny.en")
+        >>> model.cuda()  # doctest: +IGNORE_RESULT
+
+        >>> # load audios > 30 seconds
+        >>> ds = load_dataset("distil-whisper/meanwhile", "default")["test"]
+        >>> # resample to 16kHz
+        >>> ds = ds.cast_column("audio", Audio(sampling_rate=16000))
+        >>> # take first 8 audios and retrieve array
+        >>> audio = ds[:8]["audio"]
+        >>> audio = [x["array"] for x in audio]
+
+        >>> # make sure to NOT truncate the input audio, to return the `attention_mask` and to pad to the longest audio
+        >>> inputs = processor(audio, return_tensors="pt", truncation=False, padding="longest", return_attention_mask=True, sampling_rate=16_000)
+        >>> inputs = inputs.to("cuda", torch.float32)
+
+        >>> # transcribe audio to ids
+        >>> generated_ids = model.generate(**inputs)
+
+        >>> transcription = processor.batch_decode(generated_ids, skip_special_tokens=True)
+        >>> transcription[0]
+        " Folks, if you watch the show, you know, I spent a lot of time right over there. Patiently and astutely scrutinizing the boxwood and mahogany chest set of the day's biggest stories developing the central headline pawns, definitely maneuvering an oso topical night to F6, fainting a classic Sicilian, nade door variation on the news, all the while seeing eight moves deep and patiently marshalling the latest press releases into a fisher's shows in Lip Nitsky attack that culminates in the elegant lethal slow-played, all-passant checkmate that is my nightly monologue.

Meanwhile."
+        ```
+
+        - *Shortform transcription*: If passed mel input features are <= 30 seconds, there are two possibilities:
+            - `return_timestamps=False`: the whole audio will be transcribed with a single call to GenerationMixin's [`~generation.GenerationMixin.generate`].
+            - `return_timestamps=True`: the audio will be transcribed using the same logic as long-form transcription.

+            generation_config (`~generation.GenerationConfig`, *optional*):
+                The generation configuration to be used as base parametrization for the generation call. `**kwargs`

+    This model inherits from [`FlaxPreTrainedModel`]. Check the superclass documentation for the generic methods the

+    [flax.nn.Module](https://flax.readthedocs.io/en/latest/_autosummary/flax.nn.module.html) subclass. Use it as a
+    regular Flax Module and refer to the Flax documentation for all matter related to general usage and behavior.
+    Finally, this model supports inherent JAX features such as:
+    - [Just-In-Time (JIT) compilation](https://jax.readthedocs.io/en/latest/jax.html#just-in-time-compilation-jit)
+    - [Automatic Differentiation](https://jax.readthedocs.io/en/latest/jax.html#automatic-differentiation)
+    - [Vectorization](https://jax.readthedocs.io/en/latest/jax.html#vectorization-vmap)
+    - [Parallelization](https://jax.readthedocs.io/en/latest/jax.html#parallelization-pmap)

+        config ([`WhisperConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~FlaxPreTrainedModel.from_pretrained`] method to load the model weights.
+        dtype (`jax.numpy.dtype`, *optional*, defaults to `jax.numpy.float32`):
+            The data type of the computation. Can be one of `jax.numpy.float32`, `jax.numpy.float16` (on GPUs) and
+            `jax.numpy.bfloat16` (on TPUs). This can be used to enable mixed-precision training or half-precision
+            inference on GPUs or TPUs. If specified all the computation will be performed with the given `dtype`.
+            **Note that this only specifies the dtype of the computation and does not influence the dtype of model
+            parameters.** If you wish to change the dtype of the model parameters, see [`~FlaxPreTrainedModel.to_fp16`]

+    Args:
+        input_features (`tf.Tensor` of shape `(batch_size, feature_size, sequence_length)`):
+            Float values of fbank features extracted from the raw speech waveform. Raw speech waveform can be obtained
+            by loading a `.flac` or `.wav` audio file into an array of type `List[float]` or a `numpy.ndarray`, *e.g.*
+            via the soundfile library (`pip install soundfile`). To prepare the array into `input_features`, the
+            [`AutoFeatureExtractor`] should be used for extracting the fbank features, padding and conversion into a
+            tensor of type `tf.Tensor`. See [`~WhisperFeatureExtractor.__call__`]
+        decoder_input_ids (`tf.Tensor` of shape `(batch_size, target_sequence_length)`, *optional*):
+            Indices of decoder input sequence tokens in the vocabulary.
+
+            Indices can be obtained using [`SpeechToTextTokenizer`]. See [`PreTrainedTokenizer.encode`] and
+            [`PreTrainedTokenizer.__call__`] for details.
+
+            [What are decoder input IDs?](../glossary#decoder-input-ids)
+
+            SpeechToText uses the `eos_token_id` as the starting token for `decoder_input_ids` generation. If
+            `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
+            `past_key_values`).
+        decoder_attention_mask (`tf.Tensor` of shape `(batch_size, target_sequence_length)`, *optional*):
+            Default behavior: generate a tensor that ignores pad tokens in `decoder_input_ids`. Causal mask will also
+            be used by default.
+
+            If you want to change padding behavior, you should read
+            [`modeling_whisper._prepare_decoder_attention_mask`] and modify to your needs. See diagram 1 in [the
+            paper](https://arxiv.org/abs/1910.13461) for more information on the default strategy.
+        head_mask (`tf.Tensor` of shape `(encoder_layers, encoder_attention_heads)`, *optional*):
+            Mask to nullify selected heads of the attention modules in the encoder. Mask values selected in `[0, 1]`:
+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
+
+        decoder_head_mask (`tf.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, *optional*):
+            Mask to nullify selected heads of the attention modules in the decoder. Mask values selected in `[0, 1]`:
+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
+
+        cross_attn_head_mask (`tf.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, *optional*):
+            Mask to nullify selected heads of the cross-attention modules. Mask values selected in `[0, 1]`:
+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
+
+        encoder_outputs (`tuple(tuple(tf.Tensor)`, *optional*):
+            Tuple consists of (`last_hidden_state`, *optional*: `hidden_states`, *optional*: `attentions`)
+            `last_hidden_state` of shape `(batch_size, sequence_length, hidden_size)`, *optional*) is a sequence of
+            hidden-states at the output of the last layer of the encoder. Used in the cross-attention of the decoder.
+        past_key_values (`tuple(tuple(tf.Tensor))`, *optional*, returned when `use_cache=True` is passed or when `config.use_cache=True`):
+            Tuple of `tuple(tf.Tensor)` of length `config.n_layers`, with each tuple having 2 tensors of shape
+            `(batch_size, num_heads, sequence_length, embed_size_per_head)`) and 2 additional tensors of shape
+            `(batch_size, num_heads, encoder_sequence_length, embed_size_per_head)`.
+
+            Contains pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention
+            blocks) that can be used (see `past_key_values` input) to speed up sequential decoding.
+
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
+            don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all
+            `decoder_input_ids` of shape `(batch_size, sequence_length)`.
+        decoder_inputs_embeds (`tf.Tensor` of shape `(batch_size, target_sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `decoder_input_ids` you can choose to directly pass an embedded
+            representation. If `past_key_values` is used, optionally only the last `decoder_inputs_embeds` have to be
+            input (see `past_key_values`). This is useful if you want more control over how to convert
+            `decoder_input_ids` indices into associated vectors than the model's internal embedding lookup matrix.
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+            `past_key_values`).
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for

+            encoder_hidden_states (`tf.Tensor` of shape `(batch_size, encoder_sequence_length, hidden_size)`, *optional*):

+                of the decoder.
+            head_mask (`tf.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, *optional*):
+                Mask to nullify selected heads of the attention modules. Mask values selected in `[0, 1]`:
+
+                - 1 indicates the head is **not masked**,

+                on hidden heads. Mask values selected in `[0, 1]`:
+
+                - 1 indicates the head is **not masked**,
+                - 0 indicates the head is **masked**.
+
+            past_key_values (`tuple(tuple(tf.Tensor))`, *optional*, returned when `use_cache=True` is passed or when `config.use_cache=True`):
+                Tuple of `tuple(tf.Tensor)` of length `config.n_layers`, with each tuple having 2 tensors of shape
+                `(batch_size, num_heads, sequence_length, embed_size_per_head)`) and 2 additional tensors of shape
+                `(batch_size, num_heads, encoder_sequence_length, embed_size_per_head)`.
+
+                Contains pre-computed hidden-states (key and values in the self-attention blocks and in the
+                cross-attention blocks) that can be used (see `past_key_values` input) to speed up sequential decoding.
+
+                If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those
+                that don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of
+                all `decoder_input_ids` of shape `(batch_size, sequence_length)`.
+            inputs_embeds (`tf.Tensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
+                Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation.
+                This is useful if you want more control over how to convert `input_ids` indices into associated vectors
+                than the model's internal embedding lookup matrix.
+            output_attentions (`bool`, *optional*):
+                Whether or not to return the attentions tensors of all attention layers. See `attentions` under
+                returned tensors for more detail.
+            output_hidden_states (`bool`, *optional*):
+                Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors

+            return_dict (`bool`, *optional*):

+
+        Most generation-controlling parameters are set in `generation_config` which, if not passed, will be set to the
+        model's default generation configuration. You can override any `generation_config` by passing the corresponding
+        parameters to generate, e.g. `.generate(inputs, num_beams=4, do_sample=True)`.
+
+        For an overview of generation strategies and code examples, check out the [following
+        guide](../generation_strategies).
+
+        </Tip>
+
+        Parameters:
+            inputs (`tf.Tensor` of varying shape depending on the modality, *optional*):
+                The sequence used as a prompt for the generation or as model inputs to the encoder. If unset the method
+                initializes it with `bos_token_id` and a batch size of 1. For decoder-only models `inputs` should of in
+                the format of `input_ids`. For encoder-decoder models *inputs* can represent any of `input_ids`,
+                `input_values`, `input_features`, or `pixel_values`.
+            generation_config (`~generation.GenerationConfig`, *optional*):
+                The generation configuration to be used as base parametrization for the generation call. `**kwargs`
+                passed to generate matching the attributes of `generation_config` will override them. If
+                `generation_config` is not provided, the default will be used, which had the following loading
+                priority: 1) from the `generation_config.json` model file, if it exists; 2) from the model
+                configuration. Please note that unspecified parameters will inherit [`~generation.GenerationConfig`]'s
+                default values, whose documentation should be checked to parameterize generation.
+            logits_processor (`LogitsProcessorList`, *optional*):
+                Custom logits processors that complement the default logits processors built from arguments and
+                generation config. If a logit processor is passed that is already created with the arguments or a
+                generation config an error is thrown. This feature is intended for advanced users.
+            seed (`List[int]`, *optional*):
+                Random seed to control sampling, containing two integers, used when `do_sample` is `True`. See the
+                `seed` argument from stateless functions in `tf.random`.
+            return_timestamps (`bool`, *optional*):
+                Whether to return the timestamps with the text. This enables the `TFWhisperTimestampsLogitsProcessor`.
+            task (`str`, *optional*):
+                Task to use for generation, either "translate" or "transcribe". The `model.config.forced_decoder_ids`
+                will be updated accordingly.
+            language (`str`, *optional*):
+                Language token to use for generation, can be either in the form of `<|en|>`, `en` or `english`. You can
+                find all the possible language tokens in the `model.generation_config.lang_to_id` dictionary.
+            is_multilingual (`bool`, *optional*):
+                Whether or not the model is multilingual.
+            prompt_ids (`tf.Tensor`, *optional*):
+                Rank-1 tensor of token IDs created by passing text to [`~WhisperProcessor.get_prompt_ids`] that is
+                provided as a prompt to each chunk. This can be used to provide or "prompt-engineer" a context for
+                transcription, e.g. custom vocabularies or proper nouns to make it more likely to predict those words
+                correctly. It cannot be used in conjunction with `decoder_start_token_id` as it overwrites this value.
+            return_token_timestamps (`bool`, *optional*):
+                Whether to return token-level timestamps with the text. This can be used with or without the
+                `return_timestamps` option. To get word-level timestamps, use the tokenizer to group the tokens into
+                words.
+            kwargs (`Dict[str, Any]`, *optional*):
+                Ad hoc parametrization of `generate_config` and/or additional model-specific kwargs that will be
+                forwarded to the `forward` function of the model. If the model is an encoder-decoder model, encoder
+                specific kwargs should not be prefixed and decoder specific kwargs should be prefixed with *decoder_*.
+
+        Return:
+            [`~utils.ModelOutput`] or `tf.Tensor`: A [`~utils.ModelOutput`] (if `return_dict_in_generate=True` or when
+            `config.return_dict_in_generate=True`) or a `tf.Tensor`.
+

+
+            Indices can be obtained using [`WhisperTokenizer`]. See [`PreTrainedTokenizer.encode`] and

+
+            [What are decoder input IDs?](../glossary#decoder-input-ids)
+
+            Whisper uses the `decoder_start_token_id` as the starting token for `decoder_input_ids` generation. If
+            `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
+            `past_key_values`).
+        decoder_attention_mask (`torch.LongTensor` of shape `(batch_size, target_sequence_length)`, *optional*):
+            Default behavior: generate a tensor that ignores pad tokens in `decoder_input_ids`. Causal mask will also
+            be used by default.
+
+            If you want to change padding behavior, you should read
+            [`modeling_whisper._prepare_decoder_attention_mask`] and modify to your needs. See diagram 1 in [the BART
+            paper](https://arxiv.org/abs/1910.13461) for more information on the default strategy.
+        head_mask (`torch.Tensor` of shape `(encoder_layers, encoder_attention_heads)`, *optional*):
+            Mask to nullify selected heads of the attention modules in the encoder. Mask values selected in `[0, 1]`:
+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
+
+        decoder_head_mask (`torch.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, *optional*):

+
+            - 1 indicates the head is **not masked**,

+
+        cross_attn_head_mask (`torch.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, *optional*):
+            Mask to nullify selected heads of the cross-attention modules. Mask values selected in `[0, 1]`:
+

+            `last_hidden_state` of shape `(batch_size, sequence_length, hidden_size)`, *optional*) is a sequence of
+            hidden-states at the output of the last layer of the encoder. Used in the cross-attention of the decoder.
+        past_key_values (`EncoderDecoderCache` or `tuple(tuple(torch.FloatTensor))`, *optional*):
+            Pre-computed hidden-states that can be used to speed up auto-regressive (sequential) decoding. There are
+            four sets of pre-computed hidden-states: key and values states in the self-attention blocks (2) and
+            in the cross-attention blocks (2). The `past_key_values` are returned when `use_cache=True` is passed or
+            when `config.use_cache=True`
+
+            Two formats are allowed:
+            - An [`~cache_utils.EncoderDecoderCache`] instance;
+            - Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of shape
+            `(batch_size, num_heads, sequence_length, embed_size_per_head)`) and 2 additional tensors of shape
+            `(batch_size, num_heads, encoder_sequence_length, embed_size_per_head)`.
+
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
+            don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all
+            `decoder_input_ids` of shape `(batch_size, sequence_length)`.
+        decoder_inputs_embeds (`torch.FloatTensor` of shape `(batch_size, target_sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `decoder_input_ids` you can choose to directly pass an embedded
+            representation. If `past_key_values` is used, optionally only the last `decoder_inputs_embeds` have to be
+            input (see `past_key_values`). This is useful if you want more control over how to convert
+            `decoder_input_ids` indices into associated vectors than the model's internal embedding lookup matrix.
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see

+

+        normalizer_file (`str`, *optional*):
+            Path to the normalizer_file file.
+        tokenizer_file (`str`, *optional*):
+            Path to [tokenizers](https://github.com/huggingface/tokenizers) file (generally has a .json extension) that
+            contains everything needed to load the tokenizer.
+        unk_token (`str`, *optional*, defaults to `"<|endoftext|>"`):
+            The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
+            token instead.
+        bos_token (`str`, *optional*, defaults to `"<|endoftext|>"`):
+            The beginning of sequence token. The `decoder_start_token_id` is used to set the first token as
+            `"<|startoftranscript|>"` when generating.
+        eos_token (`str`, *optional*, defaults to `"<|endoftext|>"`):
+            The end of sequence token.
+        add_prefix_space (`bool`, *optional*, defaults to `False`):
+            Whether or not to add an initial space to the input. This allows to treat the leading word just as any
+            other word. (Whisper tokenizer detect beginning of words by the preceding space).
+        language (`str`, *optional*):
+            The language of the transcription text. The corresponding language id token is appended to the start of the
+            sequence for multilingual speech recognition and speech translation tasks, e.g. for Spanish the token
+            `"<|es|>"` is appended to the start of sequence. This should be used for multilingual fine-tuning only.
+        task (`str`, *optional*):
+            Task identifier to append at the start of sequence (if any). This should be used for mulitlingual
+            fine-tuning, with `"transcribe"` for speech recognition and `"translate"` for speech translation.
+        predict_timestamps (`bool`, *optional*, defaults to `False`):
+            Whether to omit the `<|notimestamps|>` token at the start of the sequence.

+    [`XCLIPConfig`] is the configuration class to store the configuration of a [`XCLIPModel`]. It is used to
+    instantiate X-CLIP model according to the specified arguments, defining the text model and vision model configs.
+    Instantiating a configuration with the defaults will yield a similar configuration to that of the X-CLIP
+    [microsoft/xclip-base-patch32](https://huggingface.co/microsoft/xclip-base-patch32) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        text_config (`dict`, *optional*):
+            Dictionary of configuration options used to initialize [`XCLIPTextConfig`].
+        vision_config (`dict`, *optional*):
+            Dictionary of configuration options used to initialize [`XCLIPVisionConfig`].
+        projection_dim (`int`, *optional*, defaults to 512):
+            Dimensionality of text and vision projection layers.
+        prompt_layers (`int`, *optional*, defaults to 2):
+            Number of layers in the video specific prompt generator.
+        prompt_alpha (`float`, *optional*, defaults to 0.1):
+            Alpha value to use in the video specific prompt generator.
+        prompt_hidden_act (`str` or `function`, *optional*, defaults to `"quick_gelu"`):
+            The non-linear activation function (function or string) in the video specific prompt generator. If string,
+            `"gelu"`, `"relu"`, `"selu"` and `"gelu_new"` `"quick_gelu"` are supported.
+        prompt_num_attention_heads (`int`, *optional*, defaults to 8):
+            Number of attention heads in the cross-attention of the video specific prompt generator.
+        prompt_attention_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout probability for the attention layers in the video specific prompt generator.
+        prompt_projection_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout probability for the projection layers in the video specific prompt generator.
+        logit_scale_init_value (`float`, *optional*, defaults to 2.6592):
+            The inital value of the *logit_scale* parameter. Default is used as per the original XCLIP implementation.

+    defaults will yield a similar configuration to that of the XGLM
+    [facebook/xglm-564M](https://huggingface.co/facebook/xglm-564M) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the

+
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 256008):
+            Vocabulary size of the XGLM model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`XGLMModel`] or [`FlaxXGLMModel`].
+        max_position_embeddings (`int`, *optional*, defaults to 2048):
+            The maximum sequence length that this model might ever be used with. Typically set this to something large
+            just in case (e.g., 512 or 1024 or 2048).

+            Dimension of the layers and the pooler layer.
+        ffn_dim (`int`, *optional*, defaults to 4096):
+            Dimension of the "intermediate" (often named feed-forward) layer in decoder.
+        num_layers (`int`, *optional*, defaults to 24):
+            Number of hidden layers Transformer decoder.
+        attention_heads (`int`, *optional*, defaults to 16):
+            Number of attention heads for each attention layer in the Transformer decoder.
+        activation_function (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"silu"` and `"gelu_new"` are supported.
+        dropout (`float`, *optional*, defaults to 0.1):
+            The dropout probability for all fully connected layers in the embeddings, dencoder, and pooler.
+        attention_dropout (`float`, *optional*, defaults to 0.1):
+            The dropout ratio for the attention probabilities.
+        activation_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for activations inside the fully connected layer.
+        layerdrop (`float`, *optional*, defaults to 0.0):
+            The LayerDrop probability for the encoder. See the [LayerDrop paper](see https://arxiv.org/abs/1909.11556)
+            for more details.
+        init_std (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        scale_embedding (`bool`, *optional*, defaults to `True`):
+            Scale embeddings by diving by sqrt(d_model).
+        use_cache (`bool`, *optional*, defaults to `True`):

+    This model inherits from [`FlaxPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a Flax Linen
+    [flax.nn.Module](https://flax.readthedocs.io/en/latest/_autosummary/flax.nn.module.html) subclass. Use it as a
+    regular Flax Module and refer to the Flax documentation for all matter related to general usage and behavior.
+
+    Finally, this model supports inherent JAX features such as:
+
+    - [Just-In-Time (JIT) compilation](https://jax.readthedocs.io/en/latest/jax.html#just-in-time-compilation-jit)
+    - [Automatic Differentiation](https://jax.readthedocs.io/en/latest/jax.html#automatic-differentiation)
+    - [Vectorization](https://jax.readthedocs.io/en/latest/jax.html#vectorization-vmap)
+    - [Parallelization](https://jax.readthedocs.io/en/latest/jax.html#parallelization-pmap)
+
+    Parameters:
+        config ([`XGLMConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~FlaxPreTrainedModel.from_pretrained`] method to load the model weights.
+        dtype (`jax.numpy.dtype`, *optional*, defaults to `jax.numpy.float32`):
+            The data type of the computation. Can be one of `jax.numpy.float32`, `jax.numpy.float16` (on GPUs) and
+            `jax.numpy.bfloat16` (on TPUs).
+
+            This can be used to enable mixed-precision training or half-precision inference on GPUs or TPUs. If
+            specified all the computation will be performed with the given `dtype`.
+
+            **Note that this only specifies the dtype of the computation and does not influence the dtype of model

+    This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it
+    as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and
+    behavior.
+
+    <Tip>
+
+    TensorFlow models and layers in `transformers` accept two formats as input:
+
+    - having all inputs as keyword arguments (like PyTorch models), or
+    - having all inputs as a list, tuple or dict in the first positional argument.
+
+    The reason the second format is supported is that Keras methods prefer this format when passing inputs to models
+    and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just
+    pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second
+    format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with
+    the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first
+    positional argument:
+
+    - a single Tensor with `input_ids` only and nothing else: `model(input_ids)`
+    - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
+    `model([input_ids, attention_mask])` or `model([input_ids, attention_mask, token_type_ids])`
+    - a dictionary with one or several input Tensors associated to the input names given in the docstring:
+    `model({"input_ids": input_ids, "token_type_ids": token_type_ids})`
+
+    Note that when creating models and layers with
+    [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry
+    about any of this, as you can just pass inputs like you would to any other Python function!

+            Sequence of hidden-states at the output of the last layer of the encoder. Used in the cross-attention of
+            the decoder.
+        encoder_attention_mask (`torch.LongTensor` of shape `(batch_size, encoder_sequence_length)`, *optional*):

+            [What are attention masks?](../glossary#attention-mask)
+        head_mask (`torch.Tensor` of shape `(num_layers, attention_heads)`, *optional*):

+
+            - 1 indicates the head is **not masked**,

+
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that

+        inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation.
+            This is useful if you want more control over how to convert `input_ids` indices into associated vectors
+            than the model's internal embedding lookup matrix.
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned

+    This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it
+    as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and
+    behavior.
+
+    <Tip>
+
+    TensorFlow models and layers in `transformers` accept two formats as input:
+
+    - having all inputs as keyword arguments (like PyTorch models), or
+    - having all inputs as a list, tuple or dict in the first positional argument.
+
+    The reason the second format is supported is that Keras methods prefer this format when passing inputs to models
+    and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just
+    pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second
+    format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with
+    the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first
+    positional argument:
+
+    - a single Tensor with `input_ids` only and nothing else: `model(input_ids)`
+    - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
+    `model([input_ids, attention_mask])` or `model([input_ids, attention_mask, token_type_ids])`
+    - a dictionary with one or several input Tensors associated to the input names given in the docstring:
+    `model({"input_ids": input_ids, "token_type_ids": token_type_ids})`
+
+    Note that when creating models and layers with
+    [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry
+    about any of this, as you can just pass inputs like you would to any other Python function!
+
+    </Tip>
+
+    Parameters:
+        config ([`XLMConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+    Args:
+        input_ids (`Numpy array` or `tf.Tensor` of shape `({0})`):
+            Indices of input sequence tokens in the vocabulary.
+
+            Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.__call__`] and
+            [`PreTrainedTokenizer.encode`] for details.
+
+            [What are input IDs?](../glossary#input-ids)
+        attention_mask (`Numpy array` or `tf.Tensor` of shape `({0})`, *optional*):
+            Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
+
+            - 1 for tokens that are **not masked**,
+            - 0 for tokens that are **masked**.
+
+            [What are attention masks?](../glossary#attention-mask)
+        langs (`tf.Tensor` or `Numpy array` of shape `({0})`, *optional*):
+            A parallel sequence of tokens to be used to indicate the language of each token in the input. Indices are
+            languages ids which can be obtained from the language names by using two conversion mappings provided in
+            the configuration of the model (only provided for multilingual models). More precisely, the *language name
+            to language id* mapping is in `model.config.lang2id` (which is a dictionary string to int) and the
+            *language id to language name* mapping is in `model.config.id2lang` (dictionary int to string).
+
+            See usage examples detailed in the [multilingual documentation](../multilingual).
+        token_type_ids (`Numpy array` or `tf.Tensor` of shape `({0})`, *optional*):
+            Segment token indices to indicate first and second portions of the inputs. Indices are selected in `[0,
+            1]`:
+
+            - 0 corresponds to a *sentence A* token,
+            - 1 corresponds to a *sentence B* token.
+
+            [What are token type IDs?](../glossary#token-type-ids)
+        position_ids (`Numpy array` or `tf.Tensor` of shape `({0})`, *optional*):
+            Indices of positions of each input sequence tokens in the position embeddings. Selected in the range `[0,
+            config.max_position_embeddings - 1]`.
+
+            [What are position IDs?](../glossary#position-ids)
+        lengths (`tf.Tensor` or `Numpy array` of shape `(batch_size,)`, *optional*):
+            Length of each sentence that can be used to avoid performing attention on padding token indices. You can
+            also use *attention_mask* for the same result (see above), kept here for compatibility. Indices selected in
+            `[0, ..., input_ids.size(-1)]`.
+        cache (`Dict[str, tf.Tensor]`, *optional*):
+            Dictionary string to `tf.Tensor` that contains precomputed hidden states (key and values in the attention
+            blocks) as computed by the model (see `cache` output below). Can be used to speed up sequential decoding.
+
+            The dictionary object will be modified in-place during the forward pass to add newly computed
+            hidden-states.
+        head_mask (`Numpy array` or `tf.Tensor` of shape `(num_heads,)` or `(num_layers, num_heads)`, *optional*):
+            Mask to nullify selected heads of the self-attention modules. Mask values selected in `[0, 1]`:
+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
+
+        inputs_embeds (`tf.Tensor` of shape `({0}, hidden_size)`, *optional*):
+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
+            model's internal embedding lookup matrix.
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail. This argument can be used only in eager mode, in graph mode the value in the
+            config will be used instead.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail. This argument can be used only in eager mode, in graph mode the value in the config will be
+            used instead.
+        return_dict (`bool`, *optional*):
+            Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple. This argument can be used in
+            eager mode, in graph mode the value will always be set to True.
+        training (`bool`, *optional*, defaults to `False`):
+            Whether or not to use the model in training mode (some modules like dropout modules have different
+            behaviors between training and evaluation).

+    Construct an XLM tokenizer. Based on Byte-Pair Encoding. The tokenization process is the following:

+    - Moses preprocessing and tokenization for most supported languages.
+    - Language specific tokenization for Chinese (Jieba), Japanese (KyTea) and Thai (PyThaiNLP).
+    - Optionally lowercases and normalizes all inputs text.
+    - The arguments `special_tokens` and the function `set_special_tokens`, can be used to add additional symbols (like
+      "__classify__") to a vocabulary.
+    - The `lang2id` attribute maps the languages supported by the model with their IDs if provided (automatically set
+      for pretrained vocabularies).
+    - The `id2lang` attributes does reverse mapping if provided (automatically set for pretrained vocabularies).
+
+    This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to
+    this superclass for more information regarding those methods.

+            token instead.
+        bos_token (`str`, *optional*, defaults to `"<s>"`):
+            The beginning of sequence token that was used during pretraining. Can be used a sequence classifier token.

+            The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for
+            sequence classification or for a text and a question for question answering. It is also used as the last
+            token of a sequence built with special tokens.

+            The token used for padding, for example when batching sequences of different lengths.
+        cls_token (`str`, *optional*, defaults to `"</s>"`):
+            The classifier token which is used when doing sequence classification (classification of the whole sequence
+            instead of per-token classification). It is the first token of the sequence when built with special tokens.
+        mask_token (`str`, *optional*, defaults to `"<special1>"`):
+            The token used for masking values. This is the token used when training this model with masked language

+            - Install with `pip install jieba`
+
+        (*) The original XLM used [Stanford
+        Segmenter](https://nlp.stanford.edu/software/stanford-segmenter-2018-10-16.zip). However, the wrapper
+        (`nltk.tokenize.stanford_segmenter`) is slow due to JVM overhead, and it will be deprecated. Jieba is a lot
+        faster and pip-installable. Note there is some mismatch with the Stanford Segmenter. It should be fine if you

+        [preprocessing script](https://github.com/facebookresearch/XLM/tree/master/tools) to tokenize the sentence

+class XLMRobertaConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`XLMRobertaModel`] or a [`TFXLMRobertaModel`]. It
+    is used to instantiate a XLM-RoBERTa model according to the specified arguments, defining the model architecture.
+    Instantiating a configuration with the defaults will yield a similar configuration to that of the XLMRoBERTa
+    [FacebookAI/xlm-roberta-base](https://huggingface.co/FacebookAI/xlm-roberta-base) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 30522):
+            Vocabulary size of the XLM-RoBERTa model. Defines the number of different tokens that can be represented by
+            the `inputs_ids` passed when calling [`XLMRobertaModel`] or [`TFXLMRobertaModel`].
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimensionality of the encoder layers and the pooler layer.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        intermediate_size (`int`, *optional*, defaults to 3072):
+            Dimensionality of the "intermediate" (often named feed-forward) layer in the Transformer encoder.
+        hidden_act (`str` or `Callable`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"silu"` and `"gelu_new"` are supported.
+        hidden_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout ratio for the attention probabilities.
+        max_position_embeddings (`int`, *optional*, defaults to 512):
+            The maximum sequence length that this model might ever be used with. Typically set this to something large
+            just in case (e.g., 512 or 1024 or 2048).
+        type_vocab_size (`int`, *optional*, defaults to 2):
+            The vocabulary size of the `token_type_ids` passed when calling [`XLMRobertaModel`] or
+            [`TFXLMRobertaModel`].
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-12):
+            The epsilon used by the layer normalization layers.
+        position_embedding_type (`str`, *optional*, defaults to `"absolute"`):
+            Type of position embedding. Choose one of `"absolute"`, `"relative_key"`, `"relative_key_query"`. For
+            positional embeddings use `"absolute"`. For more information on `"relative_key"`, please refer to
+            [Self-Attention with Relative Position Representations (Shaw et al.)](https://arxiv.org/abs/1803.02155).
+            For more information on `"relative_key_query"`, please refer to *Method 4* in [Improve Transformer Models
+            with Better Relative Position Embeddings (Huang et al.)](https://arxiv.org/abs/2009.13658).
+        is_decoder (`bool`, *optional*, defaults to `False`):
+            Whether the model is used as a decoder or not. If `False`, the model is used as an encoder.
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should return the last key/values attentions (not used by all models). Only
+            relevant if `config.is_decoder=True`.
+        classifier_dropout (`float`, *optional*):
+            The dropout ratio for the classification head.
+
+    Examples:
+
+    ```python
+    >>> from transformers import XLMRobertaConfig, XLMRobertaModel

+    This model inherits from [`FlaxPreTrainedModel`]. Check the superclass documentation for the generic methods the

+
+    This model is also a
+    [flax.linen.Module](https://flax.readthedocs.io/en/latest/api_reference/flax.linen/module.html) subclass. Use it as
+    a regular Flax linen Module and refer to the Flax documentation for all matter related to general usage and
+    behavior.
+
+    Finally, this model supports inherent JAX features such as:
+
+    - [Just-In-Time (JIT) compilation](https://jax.readthedocs.io/en/latest/jax.html#just-in-time-compilation-jit)
+    - [Automatic Differentiation](https://jax.readthedocs.io/en/latest/jax.html#automatic-differentiation)

+
+    This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it
+    as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and
+    behavior.
+
+    <Tip>
+
+    TensorFlow models and layers in `transformers` accept two formats as input:
+
+    - having all inputs as keyword arguments (like PyTorch models), or
+    - having all inputs as a list, tuple or dict in the first positional argument.
+
+    The reason the second format is supported is that Keras methods prefer this format when passing inputs to models
+    and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just
+    pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second
+    format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with
+    the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first
+    positional argument:
+
+    - a single Tensor with `input_ids` only and nothing else: `model(input_ids)`
+    - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
+    `model([input_ids, attention_mask])` or `model([input_ids, attention_mask, token_type_ids])`
+    - a dictionary with one or several input Tensors associated to the input names given in the docstring:
+    `model({"input_ids": input_ids, "token_type_ids": token_type_ids})`
+
+    Note that when creating models and layers with
+    [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry
+    about any of this, as you can just pass inputs like you would to any other Python function!
+
+    </Tip>
+
+    Parameters:
+        config ([`XLMRobertaConfig`]): Model configuration class with all the parameters of the
+            model. Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+    Adapted from [`RobertaTokenizer`] and [`XLNetTokenizer`]. Based on
+    [SentencePiece](https://github.com/google/sentencepiece).
+
+    This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to
+    this superclass for more information regarding those methods.
+
+    Args:
+        vocab_file (`str`):
+            Path to the vocabulary file.
+        bos_token (`str`, *optional*, defaults to `"<s>"`):
+            The beginning of sequence token that was used during pretraining. Can be used a sequence classifier token.
+
+            <Tip>
+
+            When building a sequence using special tokens, this is not the token that is used for the beginning of
+            sequence. The token used is the `cls_token`.
+
+            </Tip>
+
+        eos_token (`str`, *optional*, defaults to `"</s>"`):
+            The end of sequence token.
+
+            <Tip>
+
+            When building a sequence using special tokens, this is not the token that is used for the end of sequence.
+            The token used is the `sep_token`.
+
+            </Tip>
+
+        sep_token (`str`, *optional*, defaults to `"</s>"`):
+            The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for
+            sequence classification or for a text and a question for question answering. It is also used as the last
+            token of a sequence built with special tokens.
+        cls_token (`str`, *optional*, defaults to `"<s>"`):
+            The classifier token which is used when doing sequence classification (classification of the whole sequence
+            instead of per-token classification). It is the first token of the sequence when built with special tokens.
+        unk_token (`str`, *optional*, defaults to `"<unk>"`):
+            The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
+            token instead.
+        pad_token (`str`, *optional*, defaults to `"<pad>"`):
+            The token used for padding, for example when batching sequences of different lengths.
+        mask_token (`str`, *optional*, defaults to `"<mask>"`):
+            The token used for masking values. This is the token used when training this model with masked language
+            modeling. This is the token which the model will try to predict.
+        sp_model_kwargs (`dict`, *optional*):
+            Will be passed to the `SentencePieceProcessor.__init__()` method. The [Python wrapper for
+            SentencePiece](https://github.com/google/sentencepiece/tree/master/python) can be used, among other things,
+            to set:
+
+            - `enable_sampling`: Enable subword regularization.
+            - `nbest_size`: Sampling parameters for unigram. Invalid for BPE-Dropout.
+
+              - `nbest_size = {0,1}`: No sampling is performed.
+              - `nbest_size > 1`: samples from the nbest_size results.
+              - `nbest_size < 0`: assuming that nbest_size is infinite and samples from the all hypothesis (lattice)
+                using forward-filtering-and-backward-sampling algorithm.
+
+            - `alpha`: Smoothing parameter for unigram sampling, and dropout probability of merge operations for
+              BPE-dropout.
+
+    Attributes:
+        sp_model (`SentencePieceProcessor`):

+    This is the configuration class to store the configuration of a [`XLMRobertaXLModel`] or a [`TFXLMRobertaXLModel`].
+    It is used to instantiate a XLM_ROBERTA_XL model according to the specified arguments, defining the model
+    architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of the
+    XLM_ROBERTA_XL [facebook/xlm-roberta-xl](https://huggingface.co/facebook/xlm-roberta-xl) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 250880):
+            Vocabulary size of the XLM_ROBERTA_XL model. Defines the number of different tokens that can be represented
+            by the `inputs_ids` passed when calling [`XLMRobertaXLModel`].
+        hidden_size (`int`, *optional*, defaults to 2560):
+            Dimensionality of the encoder layers and the pooler layer.
+        num_hidden_layers (`int`, *optional*, defaults to 36):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 32):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        intermediate_size (`int`, *optional*, defaults to 10240):
+            Dimensionality of the "intermediate" (often named feed-forward) layer in the Transformer encoder.
+        hidden_act (`str` or `Callable`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"silu"` and `"gelu_new"` are supported.
+        hidden_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout ratio for the attention probabilities.
+        max_position_embeddings (`int`, *optional*, defaults to 514):
+            The maximum sequence length that this model might ever be used with. Typically set this to something large
+            just in case (e.g., 512 or 1024 or 2048).
+        type_vocab_size (`int`, *optional*, defaults to 1):
+            The vocabulary size of the `token_type_ids` passed when calling [`XLMRobertaXLModel`] or
+            [`TFXLMRobertaXLModel`].
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-5):
+            The epsilon used by the layer normalization layers.
+        position_embedding_type (`str`, *optional*, defaults to `"absolute"`):
+            Type of position embedding. Choose one of `"absolute"`, `"relative_key"`, `"relative_key_query"`. For
+            positional embeddings use `"absolute"`. For more information on `"relative_key"`, please refer to
+            [Self-Attention with Relative Position Representations (Shaw et al.)](https://arxiv.org/abs/1803.02155).
+            For more information on `"relative_key_query"`, please refer to *Method 4* in [Improve Transformer Models
+            with Better Relative Position Embeddings (Huang et al.)](https://arxiv.org/abs/2009.13658).
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should return the last key/values attentions (not used by all models). Only
+            relevant if `config.is_decoder=True`.
+        classifier_dropout (`float`, *optional*):
+            The dropout ratio for the classification head.
+
+    Examples:

+            Contains precomputed key and value hidden states of the attention blocks. Can be used to speed up decoding.
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
+            don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all

+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 32000):
+            Vocabulary size of the XLNet model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`XLNetModel`] or [`TFXLNetModel`].
+        d_model (`int`, *optional*, defaults to 1024):
+            Dimensionality of the encoder layers and the pooler layer.
+        n_layer (`int`, *optional*, defaults to 24):
+            Number of hidden layers in the Transformer encoder.
+        n_head (`int`, *optional*, defaults to 16):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        d_inner (`int`, *optional*, defaults to 4096):
+            Dimensionality of the "intermediate" (often named feed-forward) layer in the Transformer encoder.
+        ff_activation (`str` or `Callable`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the If string, `"gelu"`, `"relu"`, `"silu"` and
+            `"gelu_new"` are supported.

+        attn_type (`str`, *optional*, defaults to `"bi"`):
+            The attention type used by the model. Set `"bi"` for XLNet, `"uni"` for Transformer-XL.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-12):
+            The epsilon used by the layer normalization layers.
+        dropout (`float`, *optional*, defaults to 0.1):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        mem_len (`int` or `None`, *optional*):
+            The number of tokens to cache. The key/value pairs that have already been pre-computed in a previous
+            forward pass won't be re-computed. See the
+            [quickstart](https://huggingface.co/transformers/quickstart.html#using-the-past) for more information.
+        reuse_len (`int`, *optional*):
+            The number of tokens in the current batch to be cached and reused in the future.
+        bi_data (`bool`, *optional*, defaults to `False`):
+            Whether or not to use bidirectional input pipeline. Usually set to `True` during pretraining and `False`
+            during finetuning.
+        clamp_len (`int`, *optional*, defaults to -1):
+            Clamp all relative distances larger than clamp_len. Setting this attribute to -1 means no clamping.
+        same_length (`bool`, *optional*, defaults to `False`):
+            Whether or not to use the same attention length for each token.
+        summary_type (`str`, *optional*, defaults to "last"):
+            Argument used when doing sequence summary. Used in the sequence classification and multiple choice models.
+
+            Has to be one of the following options:

+            Argument used when doing sequence summary. Used in the sequence classification and multiple choice models.
+
+            Pass `"tanh"` for a tanh activation to the output, any other value will result in no activation.
+        summary_proj_to_labels (`boo`, *optional*, defaults to `True`):
+            Used in the sequence classification and multiple choice models.
+
+            Whether the projection outputs should have `config.num_labels` or `config.hidden_size` classes.
+        summary_last_dropout (`float`, *optional*, defaults to 0.1):
+            Used in the sequence classification and multiple choice models.
+
+            The dropout ratio to be used after the projection and activation.
+        start_n_top (`int`, *optional*, defaults to 5):
+            Used in the SQuAD evaluation script.
+        end_n_top (`int`, *optional*, defaults to 5):
+            Used in the SQuAD evaluation script.
+        use_mems_eval (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should make use of the recurrent memory mechanism in evaluation mode.
+        use_mems_train (`bool`, *optional*, defaults to `False`):
+            Whether or not the model should make use of the recurrent memory mechanism in train mode.
+
+            <Tip>
+
+            For pretraining, it is recommended to set `use_mems_train` to `True`. For fine-tuning, it is recommended to
+            set `use_mems_train` to `False` as discussed
+            [here](https://github.com/zihangdai/xlnet/issues/41#issuecomment-505102587). If `use_mems_train` is set to
+            `True`, one has to make sure that the train batches are correctly pre-processed, *e.g.* `batch_1 = [[This
+            line is], [This is the]]` and `batch_2 = [[ the first line], [ second line]]` and that all batches are of
+            equal size.
+
+            </Tip>
+
+    Examples:
+
+    ```python
+    >>> from transformers import XLNetConfig, XLNetModel
+
+    >>> # Initializing a XLNet configuration
+    >>> configuration = XLNetConfig()
+
+    >>> # Initializing a model (with random weights) from the configuration
+    >>> model = XLNetModel(configuration)
+
+    >>> # Accessing the model configuration
+    >>> configuration = model.config

+
+    This model inherits from [`TFPreTrainedModel`]. Check the superclass documentation for the generic methods the
+    library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
+    etc.)
+
+    This model is also a [keras.Model](https://www.tensorflow.org/api_docs/python/tf/keras/Model) subclass. Use it
+    as a regular TF 2.0 Keras Model and refer to the TF 2.0 documentation for all matter related to general usage and
+    behavior.
+
+    <Tip>
+
+    TensorFlow models and layers in `transformers` accept two formats as input:
+
+    - having all inputs as keyword arguments (like PyTorch models), or
+    - having all inputs as a list, tuple or dict in the first positional argument.
+
+    The reason the second format is supported is that Keras methods prefer this format when passing inputs to models
+    and layers. Because of this support, when using methods like `model.fit()` things should "just work" for you - just
+    pass your inputs and labels in any format that `model.fit()` supports! If, however, you want to use the second
+    format outside of Keras methods like `fit()` and `predict()`, such as when creating your own layers or models with
+    the Keras `Functional` API, there are three possibilities you can use to gather all the input Tensors in the first
+    positional argument:
+
+    - a single Tensor with `input_ids` only and nothing else: `model(input_ids)`
+    - a list of varying length with one or several input Tensors IN THE ORDER given in the docstring:
+    `model([input_ids, attention_mask])` or `model([input_ids, attention_mask, token_type_ids])`
+    - a dictionary with one or several input Tensors associated to the input names given in the docstring:
+    `model({"input_ids": input_ids, "token_type_ids": token_type_ids})`
+
+    Note that when creating models and layers with
+    [subclassing](https://keras.io/guides/making_new_layers_and_models_via_subclassing/) then you don't need to worry
+    about any of this, as you can just pass inputs like you would to any other Python function!
+
+    </Tip>
+
+    Parameters:
+        config ([`XLNetConfig`]): Model configuration class with all the parameters of the model.
+            Initializing with a config file does not load the weights associated with the model, only the
+            configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

+    Args:
+        input_ids (`torch.LongTensor` of shape `({0})`):
+            Indices of input sequence tokens in the vocabulary.
+
+            Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.encode`] and
+            [`PreTrainedTokenizer.__call__`] for details.
+
+            [What are input IDs?](../glossary#input-ids)
+        attention_mask (`torch.FloatTensor` of shape `({0})`, *optional*):
+            Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
+
+            - 1 for tokens that are **not masked**,
+            - 0 for tokens that are **masked**.
+

+            they have already been computed.
+

+        perm_mask (`torch.FloatTensor` of shape `(batch_size, sequence_length, sequence_length)`, *optional*):
+            Mask to indicate the attention pattern for each input token with values selected in `[0, 1]`:
+
+            - if `perm_mask[k, i, j] = 0`, i attend to j in batch k;
+            - if `perm_mask[k, i, j] = 1`, i does not attend to j in batch k.
+
+            If not set, each token attends to all the others (full bidirectional attention). Only used during
+            pretraining (to define factorization order) or for sequential decoding (generation).
+        target_mapping (`torch.FloatTensor` of shape `(batch_size, num_predict, sequence_length)`, *optional*):
+            Mask to indicate the output tokens to use. If `target_mapping[k, i, j] = 1`, the i-th predict in batch k is
+            on the j-th token. Only used during pretraining for partial prediction or for sequential decoding
+            (generation).
+        token_type_ids (`torch.LongTensor` of shape `({0})`, *optional*):
+            Segment token indices to indicate first and second portions of the inputs. Indices are selected in `[0,
+            1]`:
+
+            - 0 corresponds to a *sentence A* token,

+            real tokens and 1 for padding which is kept for compatibility with the original code base.
+
+            Mask values selected in `[0, 1]`:
+
+            - 1 for tokens that are **masked**,
+            - 0 for tokens that are **not masked**.
+
+            You can only uses one of `input_mask` and `attention_mask`.
+        head_mask (`torch.FloatTensor` of shape `(num_heads,)` or `(num_layers, num_heads)`, *optional*):
+            Mask to nullify selected heads of the self-attention modules. Mask values selected in `[0, 1]`:
+
+            - 1 indicates the head is **not masked**,
+            - 0 indicates the head is **masked**.
+
+        inputs_embeds (`torch.FloatTensor` of shape `({0}, hidden_size)`, *optional*):
+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
+            model's internal embedding lookup matrix.
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):

+            more detail.
+        return_dict (`bool`, *optional*):

+        perm_mask (`torch.FloatTensor` of shape `(batch_size, sequence_length, sequence_length)`, *optional*):
+            Mask to indicate the attention pattern for each input token with values selected in `[0, 1]`:
+
+            - if `perm_mask[k, i, j] = 0`, i attend to j in batch k;
+            - if `perm_mask[k, i, j] = 1`, i does not attend to j in batch k.
+
+            If not set, each token attends to all the others (full bidirectional attention). Only used during

+        target_mapping (`torch.FloatTensor` of shape `(batch_size, num_predict, sequence_length)`, *optional*):
+            Mask to indicate the output tokens to use. If `target_mapping[k, i, j] = 1`, the i-th predict in batch k is
+            on the j-th token. Only used during pretraining for partial prediction or for sequential decoding
+            (generation).
+        token_type_ids (`torch.LongTensor` of shape `({0})`, *optional*):
+            Segment token indices to indicate first and second portions of the inputs. Indices are selected in `[0,

+
+            - 0 corresponds to a *sentence A* token,

+
+            Mask values selected in `[0, 1]`:
+
+            - 1 for tokens that are **masked**,

+            Mask to nullify selected heads of the self-attention modules. Mask values selected in `[0, 1]`:
+
+            - 1 indicates the head is **not masked**,

+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
+            model's internal embedding lookup matrix.
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned

+    Construct an XLNet tokenizer. Based on [SentencePiece](https://github.com/google/sentencepiece).
+
+    This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to
+    this superclass for more information regarding those methods.
+
+    Args:
+        vocab_file (`str`):
+            [SentencePiece](https://github.com/google/sentencepiece) file (generally has a .spm extension) that
+            contains the vocabulary necessary to instantiate a tokenizer.
+        do_lower_case (`bool`, *optional*, defaults to `False`):
+            Whether to lowercase the input when tokenizing.
+        remove_space (`bool`, *optional*, defaults to `True`):
+            Whether to strip the text when tokenizing (removing excess spaces before and after the string).
+        keep_accents (`bool`, *optional*, defaults to `False`):
+            Whether to keep accents when tokenizing.
+        bos_token (`str`, *optional*, defaults to `"<s>"`):
+            The beginning of sequence token that was used during pretraining. Can be used a sequence classifier token.
+
+            <Tip>
+
+            When building a sequence using special tokens, this is not the token that is used for the beginning of
+            sequence. The token used is the `cls_token`.
+
+            </Tip>
+
+        eos_token (`str`, *optional*, defaults to `"</s>"`):
+            The end of sequence token.
+
+            <Tip>
+
+            When building a sequence using special tokens, this is not the token that is used for the end of sequence.
+            The token used is the `sep_token`.
+
+            </Tip>
+
+        unk_token (`str`, *optional*, defaults to `"<unk>"`):
+            The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
+            token instead.
+        sep_token (`str`, *optional*, defaults to `"<sep>"`):
+            The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for
+            sequence classification or for a text and a question for question answering. It is also used as the last
+            token of a sequence built with special tokens.
+        pad_token (`str`, *optional*, defaults to `"<pad>"`):
+            The token used for padding, for example when batching sequences of different lengths.
+        cls_token (`str`, *optional*, defaults to `"<cls>"`):
+            The classifier token which is used when doing sequence classification (classification of the whole sequence
+            instead of per-token classification). It is the first token of the sequence when built with special tokens.
+        mask_token (`str`, *optional*, defaults to `"<mask>"`):
+            The token used for masking values. This is the token used when training this model with masked language
+            modeling. This is the token which the model will try to predict.
+        additional_special_tokens (`List[str]`, *optional*, defaults to `['<eop>', '<eod>']`):
+            Additional special tokens used by the tokenizer.
+        sp_model_kwargs (`dict`, *optional*):
+            Will be passed to the `SentencePieceProcessor.__init__()` method. The [Python wrapper for
+            SentencePiece](https://github.com/google/sentencepiece/tree/master/python) can be used, among other things,
+            to set:
+
+            - `enable_sampling`: Enable subword regularization.
+            - `nbest_size`: Sampling parameters for unigram. Invalid for BPE-Dropout.
+
+              - `nbest_size = {0,1}`: No sampling is performed.
+              - `nbest_size > 1`: samples from the nbest_size results.
+              - `nbest_size < 0`: assuming that nbest_size is infinite and samples from the all hypothesis (lattice)
+                using forward-filtering-and-backward-sampling algorithm.
+
+            - `alpha`: Smoothing parameter for unigram sampling, and dropout probability of merge operations for
+              BPE-dropout.
+
+    Attributes:
+        sp_model (`SentencePieceProcessor`):
+            The *SentencePiece* processor that is used for every conversion (string, tokens and IDs).

+class XmodConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`XmodModel`]. It is used to instantiate an X-MOD
+    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
+    defaults will yield a similar configuration to that of the
+    [facebook/xmod-base](https://huggingface.co/facebook/xmod-base) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 30522):
+            Vocabulary size of the X-MOD model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`XmodModel`].
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimensionality of the encoder layers and the pooler layer.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        intermediate_size (`int`, *optional*, defaults to 3072):
+            Dimensionality of the "intermediate" (often named feed-forward) layer in the Transformer encoder.
+        hidden_act (`str` or `Callable`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"silu"` and `"gelu_new"` are supported.
+        hidden_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout ratio for the attention probabilities.
+        max_position_embeddings (`int`, *optional*, defaults to 512):
+            The maximum sequence length that this model might ever be used with. Typically set this to something large
+            just in case (e.g., 512 or 1024 or 2048).
+        type_vocab_size (`int`, *optional*, defaults to 2):
+            The vocabulary size of the `token_type_ids` passed when calling [`XmodModel`].
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-12):
+            The epsilon used by the layer normalization layers.
+        position_embedding_type (`str`, *optional*, defaults to `"absolute"`):
+            Type of position embedding. Choose one of `"absolute"`, `"relative_key"`, `"relative_key_query"`. For
+            positional embeddings use `"absolute"`. For more information on `"relative_key"`, please refer to
+            [Self-Attention with Relative Position Representations (Shaw et al.)](https://arxiv.org/abs/1803.02155).
+            For more information on `"relative_key_query"`, please refer to *Method 4* in [Improve Transformer Models
+            with Better Relative Position Embeddings (Huang et al.)](https://arxiv.org/abs/2009.13658).
+        is_decoder (`bool`, *optional*, defaults to `False`):
+            Whether the model is used as a decoder or not. If `False`, the model is used as an encoder.
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should return the last key/values attentions (not used by all models). Only
+            relevant if `config.is_decoder=True`.
+        classifier_dropout (`float`, *optional*):
+            The dropout ratio for the classification head.
+        pre_norm (`bool`, *optional*, defaults to `False`):
+            Whether to apply layer normalization before each block.
+        adapter_reduction_factor (`int` or `float`, *optional*, defaults to 2):
+            The factor by which the dimensionality of the adapter is reduced relative to `hidden_size`.
+        adapter_layer_norm (`bool`, *optional*, defaults to `False`):
+            Whether to apply a new layer normalization before the adapter modules (shared across all adapters).
+        adapter_reuse_layer_norm (`bool`, *optional*, defaults to `True`):
+            Whether to reuse the second layer normalization and apply it before the adapter modules as well.
+        ln_before_adapter (`bool`, *optional*, defaults to `True`):
+            Whether to apply the layer normalization before the residual connection around the adapter module.
+        languages (`Iterable[str]`, *optional*, defaults to `["en_XX"]`):
+            An iterable of language codes for which adapter modules should be initialized.
+        default_language (`str`, *optional*):
+            Language code of a default language. It will be assumed that the input is in this language if no language
+            codes are explicitly passed to the forward method.
+
+    Examples:
+
+    ```python
+    >>> from transformers import XmodConfig, XmodModel
+
+    >>> # Initializing an X-MOD facebook/xmod-base style configuration
+    >>> configuration = XmodConfig()

+    This is the configuration class to store the configuration of a [`YolosModel`]. It is used to instantiate a YOLOS
+    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
+    defaults will yield a similar configuration to that of the YOLOS
+    [hustvl/yolos-base](https://huggingface.co/hustvl/yolos-base) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+

+        hidden_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-12):
+            The epsilon used by the layer normalization layers.

+        qkv_bias (`bool`, *optional*, defaults to `True`):
+            Whether to add a bias to the queries, keys and values.
+        num_detection_tokens (`int`, *optional*, defaults to 100):
+            The number of detection tokens.
+        use_mid_position_embeddings (`bool`, *optional*, defaults to `True`):
+            Whether to use the mid-layer position encodings.
+        auxiliary_loss (`bool`, *optional*, defaults to `False`):
+            Whether auxiliary decoding losses (loss at each decoder layer) are to be used.
+        class_cost (`float`, *optional*, defaults to 1):

+    r"""
+    This is the configuration class to store the configuration of a [`YosoModel`]. It is used to instantiate an YOSO
+    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
+    defaults will yield a similar configuration to that of the YOSO
+    [uw-madison/yoso-4096](https://huggingface.co/uw-madison/yoso-4096) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 50265):
+            Vocabulary size of the YOSO model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`YosoModel`].
+        hidden_size (`int`, *optional*, defaults to 768):
+            Dimension of the encoder layers and the pooler layer.
+        num_hidden_layers (`int`, *optional*, defaults to 12):
+            Number of hidden layers in the Transformer encoder.
+        num_attention_heads (`int`, *optional*, defaults to 12):
+            Number of attention heads for each attention layer in the Transformer encoder.
+        intermediate_size (`int`, *optional*, defaults to 3072):
+            Dimension of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"selu"` and `"gelu_new"` are supported.
+        hidden_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout probability for all fully connected layers in the embeddings, encoder, and pooler.
+        attention_probs_dropout_prob (`float`, *optional*, defaults to 0.1):
+            The dropout ratio for the attention probabilities.
+        max_position_embeddings (`int`, *optional*, defaults to 512):
+            The maximum sequence length that this model might ever be used with. Typically set this to something large
+            just in case (e.g., 512 or 1024 or 2048).
+        type_vocab_size (`int`, *optional*, defaults to 2):
+            The vocabulary size of the `token_type_ids` passed when calling [`YosoModel`].
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        layer_norm_eps (`float`, *optional*, defaults to 1e-12):
+            The epsilon used by the layer normalization layers.
+        position_embedding_type (`str`, *optional*, defaults to `"absolute"`):
+            Type of position embedding. Choose one of `"absolute"`, `"relative_key"`, `"relative_key_query"`.
+        use_expectation (`bool`, *optional*, defaults to `True`):
+            Whether or not to use YOSO Expectation. Overrides any effect of num_hash.
+        hash_code_len (`int`, *optional*, defaults to 9):
+            The length of hashes generated by the hash functions.
+        num_hash (`int`, *optional*, defaults to 64):
+            Number of hash functions used in [`YosoSelfAttention`].
+        conv_window (`int`, *optional*):
+            Kernel size of depth-wise convolution.
+        use_fast_hash (`bool`, *optional*, defaults to `False`):
+            Whether or not to use custom cuda kernels which perform fast random projection via hadamard transform.
+        lsh_backward (`bool`, *optional*, defaults to `True`):
+            Whether or not to perform backpropagation using Locality Sensitive Hashing.

+class ZambaConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`ZambaModel`]. It is used to instantiate a
+    Zamba model according to the specified arguments, defining the model architecture. Instantiating a configuration
+    with the defaults will yield a similar configuration to that of the Zamba-v0.1 model.
+
+    [Zyphra/Zamba-7B-v1](https://huggingface.co/Zyphra/Zamba-7B-v1)
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 32000):
+            Vocabulary size of the Zamba model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`ZambaModel`]
+        tie_word_embeddings (`bool`, *optional*, defaults to `True`):
+            Whether the model's input and output word embeddings should be tied. Note that this is only relevant if the
+            model has a output word embedding layer.
+        hidden_size (`int`, *optional*, defaults to 3712):
+            Dimension of the hidden representations.
+        attention_hidden_size (`int`, *optional*):
+            Dimension of the hidden representations of the inputs to the Attention layer.
+        intermediate_size (`int`, *optional*, defaults to 14848):
+            Dimension of the MLP representations.
+        num_hidden_layers (`int`, *optional*, defaults to 76):
+            Number of hidden layers in the model.
+        num_attention_heads (`int`, *optional*, defaults to 16):
+            Number of attention heads for each attention layer in the Transformer decoder.
+        attention_head_dim (`int`, *optional*):
+            Dimension of the attention head in the Transformer decoder.
+        num_key_value_heads (`int`, *optional*, defaults to 16):
+            This is the number of key_value heads that should be used to implement Grouped Query Attention. If
+            `num_key_value_heads=None`, the model will use Multi Head Attention (MHA), if
+            `num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
+            converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
+            by meanpooling all the original heads within that group. For more details checkout [this
+            paper](https://arxiv.org/pdf/2305.13245.pdf).
+        n_mamba_heads (`int`, *optional*, defaults to 2):
+            Number of mamba heads for each mamba layer.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the decoder.
+        hidden_mamba_act (`str` or `function`, *optional*, defaults to `"silu"`):
+            The non-linear activation function (function or string) in the mamba layer.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        rms_norm_eps (`float`, *optional*, defaults to 1e-05):
+            The epsilon used by the rms normalization layers.
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should return the last key/values attentions (not used by all models). Only
+            relevant if `config.is_decoder=True`.
+        num_logits_to_keep (`int` or `None`, *optional*, defaults to 1):
+            Number of prompt logits to calculate during generation. If `None`, all logits will be calculated. If an
+            integer value, only last `num_logits_to_keep` logits will be calculated. Default is 1 because only the
+            logits of the last prompt token are needed for generation. For long sequences, the logits for the entire
+            sequence may use a lot of memory so, setting `num_logits_to_keep=1` will reduce memory footprint
+            significantly.
+        pad_token_id (`int`, *optional*, defaults to 0):
+            The id of the padding token.
+        bos_token_id (`int`, *optional*, defaults to 1):
+            The id of the "beginning-of-sequence" token.
+        eos_token_id (`int`, *optional*, defaults to 2):
+            The id of the "end-of-sequence" token.
+        max_position_embeddings (`int`, *optional*, defaults to 4096):
+            This value doesn't have any real effect. The maximum sequence length that this model is intended to be
+            used with. It can be used with longer sequences, but performance may degrade.
+        attention_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        attn_layer_period (`int`, *optional*, defaults to 6):
+            Once in this many layers, we will have a shared attention layer
+        attn_layer_offset (`int`, *optional*, defaults to 4):
+            Offset of the shared attention layer
+        use_mamba_kernels (`bool`, *optional*, defaults to `True`):
+            Flag indicating whether or not to use the fast mamba kernels. These are available only if `mamba-ssm` and
+            `causal-conv1d` are installed, and the mamba modules are running on a CUDA device. Raises ValueError if
+            `True` and kernels are not available
+        mamba_d_state (`int`, *optional*, defaults to 16):
+            The dimension the mamba state space latents
+        mamba_d_conv (`int`, *optional*, defaults to 4):
+            The size of the mamba convolution kernel
+        mamba_expand (`int`, *optional*, defaults to 2):
+            Expanding factor (relative to hidden_size) used to determine the mamba intermediate size
+        mamba_dt_rank (`Union[int,str]`, *optional*, defaults to `"auto"`):
+            Rank of the mamba discretization projection matrix. `"auto"` means that it will default to `math.ceil(self.hidden_size / 16)`
+        time_step_min (`float`, *optional*, defaults to 0.001):
+            Minimum `time_step` used to bound `dt_proj_bias`.
+        time_step_max (`float`, *optional*, defaults to 0.1):
+            Maximum `time_step` used to bound `dt_proj_bias`.
+        time_step_floor (`float`, *optional*, defaults to 0.0001):
+            Minimum clamping value of the `dt_proj.bias` layer initialization.
+        mamba_conv_bias (`bool`, *optional*, defaults to `True`):
+            Flag indicating whether or not to use bias in the convolution layer of the mamba mixer block.
+        mamba_proj_bias (`bool`, *optional*, defaults to `False`):
+            Flag indicating whether or not to use bias in the input and output projections (["in_proj", "out_proj"]) of the mamba mixer block

+class Zamba2Config(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`Zamba2Model`]. It is used to instantiate a
+    Zamba2 model according to the specified arguments, defining the model architecture. Instantiating a configuration
+    with the defaults will yield a similar configuration to that of the Zamba2 model.
+
+    [Zyphra/Zamba2-2.7B](https://huggingface.co/Zyphra/Zamba2-2.7B)
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.

+        mamba_ngroups (`int`, *optional*, defaults to 1):
+            Number of groups for the evolution matrices of mamba 2.
+        time_step_min (`float`, *optional*, defaults to 0.001):
+            Minimum `time_step` used to bound `dt_proj.bias`.
+        time_step_max (`float`, *optional*, defaults to 0.1):
+            Maximum `time_step` used to bound `dt_proj.bias`.

+            Number of attention heads for each attention layer in the Transformer decoder.
+        num_key_value_heads (`int`, *optional*):
+            This is the number of key_value heads that should be used to implement Grouped Query Attention. If
+            `num_key_value_heads=None`, the model will use Multi Head Attention (MHA), if
+            `num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
+            converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
+            by meanpooling all the original heads within that group. For more details checkout [this
+            paper](https://arxiv.org/pdf/2305.13245.pdf).
+        attention_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        num_mem_blocks (`int`, *optional*, defaults to 1):
+            Number of unshared transformer blocks.
+        use_shared_attention_adapter (`bool`, *optional*, defaults to `False`):
+            If True, unshared adapters (formally the same as LoRA but used in the base model) will be added to the q, k, v projectors in the shared attention layers.
+        adapter_rank (`int`, *optional*, defaults to 128):
+            Rank of the adapter in the shared MLP and shared attention layers.
+        use_mem_rope (`bool`, *optional*, defaults to `False`):
+            If True, includes RoPE in the shared attention layers.
+        rope_theta (`float`, *optional*, defaults to `10000.0`):
+            The base period of the RoPE embeddings.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.

+            The epsilon used by the rms normalization layers.
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should return the last key/values attentions (not used by all models). Only
+            relevant if `config.is_decoder=True`.
+        num_logits_to_keep (`int` or `None`, *optional*, defaults to 1):
+            Number of prompt logits to calculate during generation. If `None`, all logits will be calculated. If an
+            integer value, only last `num_logits_to_keep` logits will be calculated. Default is 1 because only the
+            logits of the last prompt token are needed for generation. For long sequences, the logits for the entire
+            sequence may use a lot of memory so, setting `num_logits_to_keep=1` will reduce memory footprint
+            significantly.
+        pad_token_id (`int`, *optional*, defaults to 0):
+            The id of the padding token.
+        bos_token_id (`int`, *optional*, defaults to 1):
+            The id of the "beginning-of-sequence" token.
+        eos_token_id (`int`, *optional*, defaults to 2):
+            The id of the "end-of-sequence" token.
+        use_long_context (`bool`, *optional*, defaults to `False`):
+            Activates the context-extended version of Zamba by modifying RoPE.

+
+
+class ZoeDepthConfig(PretrainedConfig):
+    r"""
+    This is the configuration class to store the configuration of a [`ZoeDepthForDepthEstimation`]. It is used to instantiate an ZoeDepth
+    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
+    defaults will yield a similar configuration to that of the ZoeDepth
+    [Intel/zoedepth-nyu](https://huggingface.co/Intel/zoedepth-nyu) architecture.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        backbone_config (`Union[Dict[str, Any], PretrainedConfig]`, *optional*, defaults to `BeitConfig()`):
+            The configuration of the backbone model.
+        backbone (`str`, *optional*):
+            Name of backbone to use when `backbone_config` is `None`. If `use_pretrained_backbone` is `True`, this
+            will load the corresponding pretrained weights from the timm or transformers library. If `use_pretrained_backbone`
+            is `False`, this loads the backbone's config and uses that to initialize the backbone with random weights.
+        use_pretrained_backbone (`bool`, *optional*, defaults to `False`):
+            Whether to use pretrained weights for the backbone.
+        backbone_kwargs (`dict`, *optional*):
+            Keyword arguments to be passed to AutoBackbone when loading from a checkpoint
+            e.g. `{'out_indices': (0, 1, 2, 3)}`. Cannot be specified if `backbone_config` is set.
+        hidden_act (`str` or `function`, *optional*, defaults to `"gelu"`):
+            The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
+            `"relu"`, `"selu"` and `"gelu_new"` are supported.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        batch_norm_eps (`float`, *optional*, defaults to 1e-05):
+            The epsilon used by the batch normalization layers.
+        readout_type (`str`, *optional*, defaults to `"project"`):
+            The readout type to use when processing the readout token (CLS token) of the intermediate hidden states of
+            the ViT backbone. Can be one of [`"ignore"`, `"add"`, `"project"`].
+
+            - "ignore" simply ignores the CLS token.
+            - "add" passes the information from the CLS token to all other tokens by adding the representations.
+            - "project" passes information to the other tokens by concatenating the readout to all other tokens before
+              projecting the
+            representation to the original feature dimension D using a linear layer followed by a GELU non-linearity.
+        reassemble_factors (`List[int]`, *optional*, defaults to `[4, 2, 1, 0.5]`):
+            The up/downsampling factors of the reassemble layers.
+        neck_hidden_sizes (`List[str]`, *optional*, defaults to `[96, 192, 384, 768]`):
+            The hidden sizes to project to for the feature maps of the backbone.
+        fusion_hidden_size (`int`, *optional*, defaults to 256):
+            The number of channels before fusion.
+        head_in_index (`int`, *optional*, defaults to -1):
+            The index of the features to use in the heads.
+        use_batch_norm_in_fusion_residual (`bool`, *optional*, defaults to `False`):
+            Whether to use batch normalization in the pre-activate residual units of the fusion blocks.
+        use_bias_in_fusion_residual (`bool`, *optional*, defaults to `True`):
+            Whether to use bias in the pre-activate residual units of the fusion blocks.
+        num_relative_features (`int`, *optional*, defaults to 32):
+            The number of features to use in the relative depth estimation head.
+        add_projection (`bool`, *optional*, defaults to `False`):
+            Whether to add a projection layer before the depth estimation head.
+        bottleneck_features (`int`, *optional*, defaults to 256):
+            The number of features in the bottleneck layer.
+        num_attractors (`List[int], *optional*, defaults to `[16, 8, 4, 1]`):
+            The number of attractors to use in each stage.
+        bin_embedding_dim (`int`, *optional*, defaults to 128):
+            The dimension of the bin embeddings.
+        attractor_alpha (`int`, *optional*, defaults to 1000):
+            The alpha value to use in the attractor.
+        attractor_gamma (`int`, *optional*, defaults to 2):
+            The gamma value to use in the attractor.
+        attractor_kind (`str`, *optional*, defaults to `"mean"`):
+            The kind of attractor to use. Can be one of [`"mean"`, `"sum"`].
+        min_temp (`float`, *optional*, defaults to 0.0212):
+            The minimum temperature value to consider.
+        max_temp (`float`, *optional*, defaults to 50.0):
+            The maximum temperature value to consider.
+        bin_centers_type (`str`, *optional*, defaults to `"softplus"`):
+            Activation type used for bin centers. Can be "normed" or "softplus". For "normed" bin centers, linear normalization trick
+            is applied. This results in bounded bin centers. For "softplus", softplus activation is used and thus are unbounded.
+        bin_configurations (`List[dict]`, *optional*, defaults to `[{'n_bins': 64, 'min_depth': 0.001, 'max_depth': 10.0}]`):
+            Configuration for each of the bin heads.
+            Each configuration should consist of the following keys:
+            - name (`str`): The name of the bin head - only required in case of multiple bin configurations.
+            - `n_bins` (`int`): The number of bins to use.
+            - `min_depth` (`float`): The minimum depth value to consider.
+            - `max_depth` (`float`): The maximum depth value to consider.
+            In case only a single configuration is passed, the model will use a single head with the specified configuration.
+            In case multiple configurations are passed, the model will use multiple heads with the specified configurations.
+        num_patch_transformer_layers (`int`, *optional*):
+            The number of transformer layers to use in the patch transformer. Only used in case of multiple bin configurations.
+        patch_transformer_hidden_size (`int`, *optional*):
+            The hidden size to use in the patch transformer. Only used in case of multiple bin configurations.
+        patch_transformer_intermediate_size (`int`, *optional*):
+            The intermediate size to use in the patch transformer. Only used in case of multiple bin configurations.
+        patch_transformer_num_attention_heads (`int`, *optional*):
+            The number of attention heads to use in the patch transformer. Only used in case of multiple bin configurations.
+
+    Example:
+
+    ```python
+    >>> from transformers import ZoeDepthConfig, ZoeDepthForDepthEstimation
+
+    >>> # Initializing a ZoeDepth zoedepth-large style configuration
+    >>> configuration = ZoeDepthConfig()
+
+    >>> # Initializing a model from the zoedepth-large style configuration
+    >>> model = ZoeDepthForDepthEstimation(configuration)

+
+    Recommended T5 finetuning settings (https://discuss.huggingface.co/t/t5-finetuning-tips/684/3):
+
+        - Training without LR warmup or clip_threshold is not recommended.
+
+           - use scheduled LR warm-up to fixed LR
+           - use clip_threshold=1.0 (https://arxiv.org/abs/1804.04235)
+        - Disable relative updates
+        - Use scale_parameter=False
+        - Additional optimizer operations like gradient clipping should not be used alongside Adafactor
+
+    Example:
+
+    ```python
+    Adafactor(model.parameters(), scale_parameter=False, relative_step=False, warmup_init=False, lr=1e-3)
+    ```
+
+    Others reported the following combination to work well:
+
+    ```python
+    Adafactor(model.parameters(), scale_parameter=True, relative_step=True, warmup_init=True, lr=None)
+    ```
+
+    When using `lr=None` with [`Trainer`] you will most likely need to use [`~optimization.AdafactorSchedule`]
+    scheduler as following:
+
+    ```python
+    from transformers.optimization import Adafactor, AdafactorSchedule

+            If not provided, the default tokenizer for the given `model` will be loaded (if it is a string). If `model`
+            is not specified or not a string, then the default tokenizer for `config` is loaded (if it is a string).
+            However, if `config` is also not given or not a string, then the default tokenizer for the given `task`
+            will be loaded.
+        feature_extractor (`str` or [`PreTrainedFeatureExtractor`], *optional*):
+            The feature extractor that will be used by the pipeline to encode data for the model. This can be a model
+            identifier or an actual pretrained feature extractor inheriting from [`PreTrainedFeatureExtractor`].
+
+            Feature extractors are used for non-NLP models, such as Speech or Vision models as well as multi-modal
+            models. Multi-modal models will also require a tokenizer to be passed.
+
+            If not provided, the default feature extractor for the given `model` will be loaded (if it is a string). If
+            `model` is not specified or not a string, then the default feature extractor for `config` is loaded (if it
+            is a string). However, if `config` is also not given or not a string, then the default feature extractor
+            for the given `task` will be loaded.
+        image_processor (`str` or [`BaseImageProcessor`], *optional*):
+            The image processor that will be used by the pipeline to preprocess images for the model. This can be a
+            model identifier or an actual image processor inheriting from [`BaseImageProcessor`].
+
+            Image processors are used for Vision models and multi-modal models that require image inputs. Multi-modal
+            models will also require a tokenizer to be passed.
+
+            If not provided, the default image processor for the given `model` will be loaded (if it is a string). If
+            `model` is not specified or not a string, then the default image processor for `config` is loaded (if it is
+            a string).
+        processor (`str` or [`ProcessorMixin`], *optional*):
+            The processor that will be used by the pipeline to preprocess data for the model. This can be a model
+            identifier or an actual processor inheriting from [`ProcessorMixin`].
+
+            Processors are used for multi-modal models that require multi-modal inputs, for example, a model that
+            requires both text and image inputs.
+
+            If not provided, the default processor for the given `model` will be loaded (if it is a string). If `model`
+            is not specified or not a string, then the default processor for `config` is loaded (if it is a string).
+        framework (`str`, *optional*):
+            The framework to use, either `"pt"` for PyTorch or `"tf"` for TensorFlow. The specified framework must be
+            installed.
+
+            If no framework is specified, will default to the one currently installed. If no framework is specified and
+            both frameworks are installed, will default to the framework of the `model`, or to PyTorch if no model is
+            provided.
+        revision (`str`, *optional*, defaults to `"main"`):
+            When passing a task name or a string model identifier: The specific model version to use. It can be a
+            branch name, a tag name, or a commit id, since we use a git-based system for storing models and other
+            artifacts on huggingface.co, so `revision` can be any identifier allowed by git.
+        use_fast (`bool`, *optional*, defaults to `True`):
+            Whether or not to use a Fast tokenizer if possible (a [`PreTrainedTokenizerFast`]).
+        use_auth_token (`str` or *bool*, *optional*):
+            The token to use as HTTP bearer authorization for remote files. If `True`, will use the token generated
+            when running `huggingface-cli login` (stored in `~/.huggingface`).
+        device (`int` or `str` or `torch.device`):
+            Defines the device (*e.g.*, `"cpu"`, `"cuda:1"`, `"mps"`, or a GPU ordinal rank like `1`) on which this
+            pipeline will be allocated.
+        device_map (`str` or `Dict[str, Union[int, str, torch.device]`, *optional*):
+            Sent directly as `model_kwargs` (just a simpler shortcut). When `accelerate` library is present, set
+            `device_map="auto"` to compute the most optimized `device_map` automatically (see
+            [here](https://huggingface.co/docs/accelerate/main/en/package_reference/big_modeling#accelerate.cpu_offload)
+            for more information).
+
+            <Tip warning={true}>
+
+            Do not use `device_map` AND `device` at the same time as they will conflict
+
+            </Tip>
+
+        torch_dtype (`str` or `torch.dtype`, *optional*):
+            Sent directly as `model_kwargs` (just a simpler shortcut) to use the available precision for this model
+            (`torch.float16`, `torch.bfloat16`, ... or `"auto"`).
+        trust_remote_code (`bool`, *optional*, defaults to `False`):
+            Whether or not to allow for custom code defined on the Hub in their own modeling, configuration,
+            tokenization or even pipeline files. This option should only be set to `True` for repositories you trust
+            and in which you have read the code, as it will execute code present on the Hub on your local machine.
+        model_kwargs (`Dict[str, Any]`, *optional*):
+            Additional dictionary of keyword arguments passed along to the model's `from_pretrained(...,
+            **model_kwargs)` function.
+        kwargs (`Dict[str, Any]`, *optional*):
+            Additional keyword arguments passed along to the specific pipeline init (see the documentation for the
+            corresponding pipeline class for possible values).
+
+    Returns:
+        [`Pipeline`]: A suitable pipeline for the task.

+    Learn more about the basics of using a pipeline in the [pipeline tutorial](../pipeline_tutorial)
+
+    Arguments:
+        model ([`PreTrainedModel`] or [`TFPreTrainedModel`]):
+            The model that will be used by the pipeline to make predictions. This needs to be a model inheriting from
+            [`PreTrainedModel`] for PyTorch and [`TFPreTrainedModel`] for TensorFlow.
+        feature_extractor ([`SequenceFeatureExtractor`]):
+            The feature extractor that will be used by the pipeline to encode waveform for the model.
+        tokenizer ([`PreTrainedTokenizer`]):
+            The tokenizer that will be used by the pipeline to encode data for the model. This object inherits from
+            [`PreTrainedTokenizer`].
+        decoder (`pyctcdecode.BeamSearchDecoderCTC`, *optional*):
+            [PyCTCDecode's
+            BeamSearchDecoderCTC](https://github.com/kensho-technologies/pyctcdecode/blob/2fd33dc37c4111417e08d89ccd23d28e9b308d19/pyctcdecode/decoder.py#L180)
+            can be passed for language model boosted decoding. See [`Wav2Vec2ProcessorWithLM`] for more information.
+        chunk_length_s (`float`, *optional*, defaults to 0):
+            The input length for in each chunk. If `chunk_length_s = 0` then chunking is disabled (default).
+
+            <Tip>
+
+            For more information on how to effectively use `chunk_length_s`, please have a look at the [ASR chunking
+            blog post](https://huggingface.co/blog/asr-chunking).
+
+            </Tip>
+
+        stride_length_s (`float`, *optional*, defaults to `chunk_length_s / 6`):
+            The length of stride on the left and right of each chunk. Used only with `chunk_length_s > 0`. This enables
+            the model to *see* more context and infer letters better than without this context but the pipeline
+            discards the stride bits at the end to make the final reconstitution as perfect as possible.
+
+            <Tip>
+
+            For more information on how to effectively use `stride_length_s`, please have a look at the [ASR chunking
+            blog post](https://huggingface.co/blog/asr-chunking).
+
+            </Tip>
+
+        framework (`str`, *optional*):
+            The framework to use, either `"pt"` for PyTorch or `"tf"` for TensorFlow. The specified framework must be
+            installed. If no framework is specified, will default to the one currently installed. If no framework is
+            specified and both frameworks are installed, will default to the framework of the `model`, or to PyTorch if
+            no model is provided.
+        device (Union[`int`, `torch.device`], *optional*):
+            Device ordinal for CPU/GPU supports. Setting this to `None` will leverage CPU, a positive will run the
+            model on the associated CUDA device id.
+        torch_dtype (Union[`int`, `torch.dtype`], *optional*):
+            The data-type (dtype) of the computation. Setting this to `None` will use float32 precision. Set to
+            `torch.float16` or `torch.bfloat16` to use half-precision in the respective dtypes.

+                The inputs is either :
+                    - `str` that is either the filename of a local audio file, or a public URL address to download the
+                      audio file. The file will be read at the correct sampling rate to get the waveform using
+                      *ffmpeg*. This requires *ffmpeg* to be installed on the system.
+                    - `bytes` it is supposed to be the content of an audio file and is interpreted by *ffmpeg* in the
+                      same way.
+                    - (`np.ndarray` of shape (n, ) of type `np.float32` or `np.float64`)
+                        Raw audio at the correct sampling rate (no further check will be done)
+                    - `dict` form can be used to pass raw audio sampled at arbitrary `sampling_rate` and let this
+                      pipeline do the resampling. The dict must be in the format `{"sampling_rate": int, "raw":
+                      np.array}` with optionally a `"stride": (left: int, right: int)` than can ask the pipeline to
+                      treat the first `left` samples and last `right` samples to be ignored in decoding (but used at
+                      inference to provide more context to the model). Only use `stride` with CTC models.
+            return_timestamps (*optional*, `str` or `bool`):
+                Only available for pure CTC models (Wav2Vec2, HuBERT, etc) and the Whisper model. Not available for
+                other sequence-to-sequence models.
+
+                For CTC models, timestamps can take one of two formats:
+                    - `"char"`: the pipeline will return timestamps along the text for every character in the text. For
+                        instance, if you get `[{"text": "h", "timestamp": (0.5, 0.6)}, {"text": "i", "timestamp": (0.7,
+                        0.9)}]`, then it means the model predicts that the letter "h" was spoken after `0.5` and before
+                        `0.6` seconds.
+                    - `"word"`: the pipeline will return timestamps along the text for every word in the text. For
+                        instance, if you get `[{"text": "hi ", "timestamp": (0.5, 0.9)}, {"text": "there", "timestamp":
+                        (1.0, 1.5)}]`, then it means the model predicts that the word "hi" was spoken after `0.5` and
+                        before `0.9` seconds.
+
+                For the Whisper model, timestamps can take one of two formats:
+                    - `"word"`: same as above for word-level CTC timestamps. Word-level timestamps are predicted
+                        through the *dynamic-time warping (DTW)* algorithm, an approximation to word-level timestamps
+                        by inspecting the cross-attention weights.
+                    - `True`: the pipeline will return timestamps along the text for *segments* of words in the text.
+                        For instance, if you get `[{"text": " Hi there!", "timestamp": (0.5, 1.5)}]`, then it means the
+                        model predicts that the segment "Hi there!" was spoken after `0.5` and before `1.5` seconds.
+                        Note that a segment of text refers to a sequence of one or more words, rather than individual
+                        words as with word-level timestamps.
+            generate_kwargs (`dict`, *optional*):
+                The dictionary of ad-hoc parametrization of `generate_config` to be used for the generation call. For a
+                complete overview of generate, check the [following
+                guide](https://huggingface.co/docs/transformers/en/main_classes/text_generation).

+                - **chunks** (*optional(, `List[Dict]`)
+                    When using `return_timestamps`, the `chunks` will become a list containing all the various text
+                    chunks identified by the model, *e.g.* `[{"text": "hi ", "timestamp": (0.5, 0.9)}, {"text":
+                    "there", "timestamp": (1.0, 1.5)}]`. The original full text can roughly be recovered by doing

+                - An image loaded in PIL directly
+
+                The pipeline accepts either a single image or a batch of images, which must then be passed as a string.
+                Images in a batch must all be in the same format: all as http links, all as local paths, or all as PIL
+                images.
+            parameters (`Dict`, *optional*):
+                A dictionary of argument names to parameter values, to control pipeline behaviour.
+                The only parameter available right now is `timeout`, which is the length of time, in seconds,
+                that the pipeline should wait before giving up on trying to download an image.
+            timeout (`float`, *optional*, defaults to None):
+                The maximum time in seconds to wait for fetching images from the web. If None, no timeout is set and

+            dictionary, if the input is a list of several images, will return a list of dictionaries corresponding to
+            the images.

+    Document Question Answering pipeline using any `AutoModelForDocumentQuestionAnswering`. The inputs/outputs are
+    similar to the (extractive) question answering pipeline; however, the pipeline takes an image (and optional OCR'd
+    words/boxes) as input instead of text context.
+
+    Example:
+
+    ```python
+    >>> from transformers import pipeline
+
+    >>> document_qa = pipeline(model="impira/layoutlm-document-qa")
+    >>> document_qa(
+    ...     image="https://huggingface.co/spaces/impira/docquery/resolve/2359223c1837a7587402bda0f2643382a6eefeab/invoice.png",
+    ...     question="What is the invoice number?",
+    ... )
+    [{'score': 0.425, 'answer': 'us-001', 'start': 16, 'end': 16}]
+    ```
+
+    Learn more about the basics of using a pipeline in the [pipeline tutorial](../pipeline_tutorial)
+
+    This document question answering pipeline can currently be loaded from [`pipeline`] using the following task
+    identifier: `"document-question-answering"`.
+
+    The models that this pipeline can use are models that have been fine-tuned on a document question answering task.
+    See the up-to-date list of available models on
+    [huggingface.co/models](https://huggingface.co/models?filter=document-question-answering).

+        Answer the question(s) given as inputs by using the document(s). A document is defined as an image and an
+        optional list of (word, box) tuples which represent the text in the document. If the `word_boxes` are not
+        provided, it will use the Tesseract OCR engine (if available) to extract the words and boxes automatically for
+        LayoutLM-like models which require them as input. For Donut, no OCR is run.
+
+        You can invoke the pipeline several ways:
+
+        - `pipeline(image=image, question=question)`
+        - `pipeline(image=image, question=question, word_boxes=word_boxes)`
+        - `pipeline([{"image": image, "question": question}])`
+        - `pipeline([{"image": image, "question": question, "word_boxes": word_boxes}])`
+
+        Args:
+            image (`str` or `PIL.Image`):
+                The pipeline handles three types of images:
+
+                - A string containing a http link pointing to an image
+                - A string containing a local path to an image
+                - An image loaded in PIL directly
+
+                The pipeline accepts either a single image or a batch of images. If given a single image, it can be
+                broadcasted to multiple questions.
+            question (`str`):
+                A question to ask of the document.
+            word_boxes (`List[str, Tuple[float, float, float, float]]`, *optional*):
+                A list of words and bounding boxes (normalized 0->1000). If you provide this optional input, then the
+                pipeline will use these words and boxes instead of running OCR on the image to derive them for models
+                that need them (e.g. LayoutLM). This allows you to reuse OCR'd results across many invocations of the
+                pipeline without having to re-run it each time.
+            top_k (`int`, *optional*, defaults to 1):
+                The number of answers to return (will be chosen by order of likelihood). Note that we return less than
+                top_k answers if there are not enough options available within the context.
+            doc_stride (`int`, *optional*, defaults to 128):
+                If the words in the document are too long to fit with the question for the model, it will be split in
+                several chunks with some overlap. This argument controls the size of that overlap.
+            max_answer_len (`int`, *optional*, defaults to 15):
+                The maximum length of predicted answers (e.g., only answers with a shorter length are considered).
+            max_seq_len (`int`, *optional*, defaults to 384):
+                The maximum length of the total sentence (context + question) in tokens of each chunk passed to the
+                model. The context will be split in several chunks (using `doc_stride` as overlap) if needed.
+            max_question_len (`int`, *optional*, defaults to 64):
+                The maximum length of the question after tokenization. It will be truncated if needed.
+            handle_impossible_answer (`bool`, *optional*, defaults to `False`):
+                Whether or not we accept impossible as an answer.
+            lang (`str`, *optional*):
+                Language to use while running OCR. Defaults to english.
+            tesseract_config (`str`, *optional*):
+                Additional flags to pass to tesseract while running OCR.
+            timeout (`float`, *optional*, defaults to None):
+                The maximum time in seconds to wait for fetching images from the web. If None, no timeout is set and
+                the call may block forever.
+
+        Return:
+            A `dict` or a list of `dict`: Each result comes as a dictionary with the following keys:
+
+            - **score** (`float`) -- The probability associated to the answer.
+            - **start** (`int`) -- The start word index of the answer (in the OCR'd version of the input or provided
+              `word_boxes`).
+            - **end** (`int`) -- The end word index of the answer (in the OCR'd version of the input or provided
+              `word_boxes`).
+            - **answer** (`str`) -- The answer to the question.

+                  `panoptic`, `instance`, `semantic`.
+            threshold (`float`, *optional*, defaults to 0.9):

+            timeout (`float`, *optional*, defaults to None):
+                The maximum time in seconds to wait for fetching images from the web. If None, no timeout is set and

+class MaskGenerationPipeline(ChunkPipeline):
+    """
+    Automatic mask generation for images using `SamForMaskGeneration`. This pipeline predicts binary masks for an
+    image, given an image. It is a `ChunkPipeline` because you can seperate the points in a mini-batch in order to
+    avoid OOM issues. Use the `points_per_batch` argument to control the number of points that will be processed at the
+    same time. Default is `64`.
+
+    The pipeline works in 3 steps:
+        1. `preprocess`: A grid of 1024 points evenly separated is generated along with bounding boxes and point
+           labels.
+            For more details on how the points and bounding boxes are created, check the `_generate_crop_boxes`
+            function. The image is also preprocessed using the `image_processor`. This function `yields` a minibatch of
+            `points_per_batch`.
+
+        2. `forward`: feeds the outputs of `preprocess` to the model. The image embedding is computed only once.
+            Calls both `self.model.get_image_embeddings` and makes sure that the gradients are not computed, and the
+            tensors and models are on the same device.
+
+        3. `postprocess`: The most important part of the automatic mask generation happens here. Three steps
+            are induced:
+                - image_processor.postprocess_masks (run on each minibatch loop): takes in the raw output masks,
+                  resizes them according
+                to the image size, and transforms there to binary masks.
+                - image_processor.filter_masks (on each minibatch loop): uses both `pred_iou_thresh` and
+                  `stability_scores`. Also
+                applies a variety of filters based on non maximum suppression to remove bad masks.
+                - image_processor.postprocess_masks_for_amg applies the NSM on the mask to only keep relevant ones.
+
+    Example:
+
+    ```python
+    >>> from transformers import pipeline
+
+    >>> generator = pipeline(model="facebook/sam-vit-base", task="mask-generation")
+    >>> outputs = generator(
+    ...     "http://images.cocodataset.org/val2017/000000039769.jpg",
+    ... )
+
+    >>> outputs = generator(
+    ...     "https://huggingface.co/datasets/Narsil/image_dummy/raw/main/parrots.png", points_per_batch=128
+    ... )
+    ```

+        Answers queries according to a table. The pipeline accepts several types of inputs which are detailed below:
+
+        - `pipeline(table, query)`
+        - `pipeline(table, [query])`
+        - `pipeline(table=table, query=query)`
+        - `pipeline(table=table, query=[query])`
+        - `pipeline({"table": table, "query": query})`
+        - `pipeline({"table": table, "query": [query]})`
+        - `pipeline([{"table": table, "query": query}, {"table": table, "query": query}])`
+
+        The `table` argument should be a dict or a DataFrame built from that dict, containing the whole table:
+
+        Example:
+
+        ```python
+        data = {
+            "actors": ["brad pitt", "leonardo di caprio", "george clooney"],
+            "age": ["56", "45", "59"],
+            "number of movies": ["87", "53", "69"],
+            "date of birth": ["7 february 1967", "10 june 1996", "28 november 1967"],
+        }
+        ```
+
+        This dictionary can be passed in as such, or can be converted to a pandas DataFrame:
+
+        Example:
+
+        ```python
+        import pandas as pd
+
+        table = pd.DataFrame.from_dict(data)
+        ```
+
+        Args:
+            table (`pd.DataFrame` or `Dict`):
+                Pandas DataFrame or dictionary that will be converted to a DataFrame containing all the table values.
+                See above for an example of dictionary.
+            query (`str` or `List[str]`):
+                Query or list of queries that will be sent to the model alongside the table.
+            sequential (`bool`, *optional*, defaults to `False`):
+                Whether to do inference sequentially or as a batch. Batching is faster, but models like SQA require the
+                inference to be done sequentially to extract relations within sequences, given their conversational
+                nature.
+            padding (`bool`, `str` or [`~utils.PaddingStrategy`], *optional*, defaults to `False`):
+                Activates and controls padding. Accepts the following values:
+
+                - `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single
+                  sequence if provided).
+                - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum
+                  acceptable input length for the model if that argument is not provided.
+                - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different
+                  lengths).
+
+            truncation (`bool`, `str` or [`TapasTruncationStrategy`], *optional*, defaults to `False`):
+                Activates and controls truncation. Accepts the following values:
+
+                - `True` or `'drop_rows_to_fit'`: Truncate to a maximum length specified with the argument `max_length`
+                  or to the maximum acceptable input length for the model if that argument is not provided. This will
+                  truncate row by row, removing rows from the table.
+                - `False` or `'do_not_truncate'` (default): No truncation (i.e., can output batch with sequence lengths
+                  greater than the model maximum admissible input size).
+
+
+        Return:
+            A dictionary or a list of dictionaries containing results: Each result is a dictionary with the following
+            keys:
+
+            - **answer** (`str`) -- The answer of the query given the table. If there is an aggregator, the answer will
+              be preceded by `AGGREGATOR >`.
+            - **coordinates** (`List[Tuple[int, int]]`) -- Coordinates of the cells of the answers.
+            - **cells** (`List[str]`) -- List of strings made up of the answer cell values.
+            - **aggregator** (`str`) -- If the model has an aggregator, this returns the aggregator.

+    specified text prompt. When the underlying model is a conversational model, it can also accept one or more chats,
+    in which case the pipeline will operate in chat mode and will continue the chat(s) by adding its response(s).
+    Each chat takes the form of a list of dicts, where each dict contains "role" and "content" keys.
+
+    Examples:
+
+    ```python

+    >>> generator("I can't believe you did such a ", do_sample=False)

+    >>> outputs = generator("My tart needs some", num_return_sequences=4, return_full_text=False)

+
+    ```python

+    Text-to-audio generation pipeline using any `AutoModelForTextToWaveform` or `AutoModelForTextToSpectrogram`. This
+    pipeline generates an audio file from an input text and optional other conditional inputs.
+
+    Example:
+
+    ```python
+    >>> from transformers import pipeline
+
+    >>> pipe = pipeline(model="suno/bark-small")
+    >>> output = pipe("Hey it's HuggingFace on the phone!")
+
+    >>> audio = output["audio"]
+    >>> sampling_rate = output["sampling_rate"]
+    ```
+
+    Learn more about the basics of using a pipeline in the [pipeline tutorial](../pipeline_tutorial)
+
+    <Tip>
+
+    You can specify parameters passed to the model by using [`TextToAudioPipeline.__call__.forward_params`] or
+    [`TextToAudioPipeline.__call__.generate_kwargs`].
+
+    Example:
+
+    ```python
+    >>> from transformers import pipeline
+
+    >>> music_generator = pipeline(task="text-to-audio", model="facebook/musicgen-small", framework="pt")
+
+    >>> # diversify the music generation by adding randomness with a high temperature and set a maximum music length
+    >>> generate_kwargs = {

+    ...     "temperature": 0.7,
+    ...     "max_new_tokens": 35,

+
+    >>> outputs = music_generator("Techno music with high melodic riffs", generate_kwargs=generate_kwargs)
+    ```
+
+    </Tip>
+
+    This pipeline can currently be loaded from [`pipeline`] using the following task identifiers: `"text-to-speech"` or

+                If multiple images and questions are given, each and every question will be broadcasted to all images
+                (same effect as a Cartesian product)
+            top_k (`int`, *optional*, defaults to 5):
+                The number of top labels that will be returned by the pipeline. If the provided number is higher than
+                the number of labels available in the model configuration, it will default to the number of labels.

+                The maximum time in seconds to wait for fetching images from the web. If None, no timeout is set and
+                the call may block forever.

+    NLI-based zero-shot classification pipeline using a `ModelForSequenceClassification` trained on NLI (natural
+    language inference) tasks. Equivalent of `text-classification` pipelines, but these models don't require a
+    hardcoded number of potential classes, they can be chosen at runtime. It usually means it's slower but it is
+    **much** more flexible.
+
+    Any combination of sequences and labels can be passed and each combination will be posed as a premise/hypothesis
+    pair and passed to the pretrained model. Then, the logit for *entailment* is taken as the logit for the candidate
+    label being valid. Any NLI model can be used, but the id of the *entailment* label must be included in the model
+    config's :attr:*~transformers.PretrainedConfig.label2id*.
+
+    Example:
+
+    ```python
+    >>> from transformers import pipeline
+
+    >>> oracle = pipeline(model="facebook/bart-large-mnli")
+    >>> oracle(
+    ...     "I have a problem with my iphone that needs to be resolved asap!!",
+    ...     candidate_labels=["urgent", "not urgent", "phone", "tablet", "computer"],
+    ... )
+    {'sequence': 'I have a problem with my iphone that needs to be resolved asap!!', 'labels': ['urgent', 'phone', 'computer', 'not urgent', 'tablet'], 'scores': [0.504, 0.479, 0.013, 0.003, 0.002]}

+    """
+    This class extends *unittest.TestCase* with additional features.
+
+    Feature 1: A set of fully resolved important file and dir path accessors.
+
+    In tests often we need to know where things are relative to the current test file, and it's not trivial since the
+    test could be invoked from more than one directory or could reside in sub-directories with different depths. This
+    class solves this problem by sorting out all the basic paths and provides easy accessors to them:
+
+    - `pathlib` objects (all fully resolved):
+
+       - `test_file_path` - the current test file path (=`__file__`)
+       - `test_file_dir` - the directory containing the current test file
+       - `tests_dir` - the directory of the `tests` test suite
+       - `examples_dir` - the directory of the `examples` test suite
+       - `repo_root_dir` - the directory of the repository
+       - `src_dir` - the directory of `src` (i.e. where the `transformers` sub-dir resides)
+
+    - stringified paths---same as above but these return paths as strings, rather than `pathlib` objects:
+
+       - `test_file_path_str`
+       - `test_file_dir_str`
+       - `tests_dir_str`
+       - `examples_dir_str`
+       - `repo_root_dir_str`
+       - `src_dir_str`
+
+    Feature 2: Flexible auto-removable temporary dirs which are guaranteed to get removed at the end of test.
+
+    1. Create a unique temporary dir:
+
+    ```python
+    def test_whatever(self):
+        tmp_dir = self.get_auto_remove_tmp_dir()
+    ```
+
+    `tmp_dir` will contain the path to the created temporary dir. It will be automatically removed at the end of the
+    test.
+
+
+    2. Create a temporary dir of my choice, ensure it's empty before the test starts and don't
+    empty it after the test.
+
+    ```python
+    def test_whatever(self):
+        tmp_dir = self.get_auto_remove_tmp_dir("./xxx")
+    ```
+
+    This is useful for debug when you want to monitor a specific directory and want to make sure the previous tests
+    didn't leave any data in there.
+
+    3. You can override the first two options by directly overriding the `before` and `after` args, leading to the
+        following behavior:
+
+    `before=True`: the temporary dir will always be cleared at the beginning of the test.
+
+    `before=False`: if the temporary dir already existed, any existing files will remain there.
+
+    `after=True`: the temporary dir will always be deleted at the end of the test.
+
+    `after=False`: the temporary dir will always be left intact at the end of the test.
+
+    Note 1: In order to run the equivalent of `rm -r` safely, only subdirs of the project repository checkout are
+    allowed if an explicit `tmp_dir` is used, so that by mistake no `/tmp` or similar important part of the filesystem
+    will get nuked. i.e. please always pass paths that start with `./`
+
+    Note 2: Each test can register multiple temporary dirs and they all will get auto-removed, unless requested
+    otherwise.
+
+    Feature 3: Get a copy of the `os.environ` object that sets up `PYTHONPATH` specific to the current test suite. This
+    is useful for invoking external programs from the test suite - e.g. distributed training.
+

+
+    Args:

+            A Jinja template string that will be used to format lists of chat messages. See
+            https://huggingface.co/docs/transformers/chat_templating for a full description.
+        model_input_names (`List[string]`, *optional*):
+            The list of inputs accepted by the forward pass of the model (like `"token_type_ids"` or
+            `"attention_mask"`). Default value is picked from the class attribute of the same name.
+        bos_token (`str` or `tokenizers.AddedToken`, *optional*):
+            A special token representing the beginning of a sentence. Will be associated to `self.bos_token` and
+            `self.bos_token_id`.
+        eos_token (`str` or `tokenizers.AddedToken`, *optional*):

+            `self.unk_token_id`.
+        sep_token (`str` or `tokenizers.AddedToken`, *optional*):
+            A special token separating two different sentences in the same input (used by BERT for instance). Will be
+            associated to `self.sep_token` and `self.sep_token_id`.
+        pad_token (`str` or `tokenizers.AddedToken`, *optional*):
+            A special token used to make arrays of tokens the same size for batching purpose. Will then be ignored by
+            attention mechanisms or loss computation. Will be associated to `self.pad_token` and `self.pad_token_id`.
+        cls_token (`str` or `tokenizers.AddedToken`, *optional*):
+            A special token representing the class of the input (used by BERT for instance). Will be associated to
+            `self.cls_token` and `self.cls_token_id`.
+        mask_token (`str` or `tokenizers.AddedToken`, *optional*):

+        additional_special_tokens (tuple or list of `str` or `tokenizers.AddedToken`, *optional*):
+            A tuple or a list of additional special tokens. Add them here to ensure they are skipped when decoding with
+            `skip_special_tokens` is set to True. If they are not part of the vocabulary, they will be added at the end
+            of the vocabulary.
+        clean_up_tokenization_spaces (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should cleanup the spaces that were added when splitting the input text during the

+        split_special_tokens (`bool`, *optional*, defaults to `False`):
+            Whether or not the special tokens should be split during the tokenization process. Passing will affect the
+            internal state of the tokenizer. The default behavior is to not split special tokens. This means that if
+            `<s>` is the `bos_token`, then `tokenizer.tokenize("<s>") = ['<s>`]. Otherwise, if
+            `split_special_tokens=True`, then `tokenizer.tokenize("<s>")` will be give `['<','s', '>']`.

+                 index) among:
+

+                  sequence if provided).
+                - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum
+                  acceptable input length for the model if that argument is not provided.
+                - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different

+            truncation (`bool`, defaults to `False`):
+                Whether to truncate sequences at the maximum length. Has no effect if tokenize is `False`.

+                If set, will return tensors of a particular framework. Has no effect if tokenize is `False`. Acceptable
+                values are:
+                - `'tf'`: Return TensorFlow `tf.Tensor` objects.
+                - `'pt'`: Return PyTorch `torch.Tensor` objects.

+            return_assistant_tokens_mask (`bool`, defaults to `False`):

+            resume_download:
+                Deprecated and ignored. All downloads are now resumed by default when possible.

+            token (`str` or *bool*, *optional*):
+                The token to use as HTTP bearer authorization for remote files. If `True`, will use the token generated

+                The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a
+                git-based system for storing models and other artifacts on huggingface.co, so `revision` can be any
+                identifier allowed by git.

+            inputs (additional positional arguments, *optional*):
+                Will be passed along to the Tokenizer `__init__` method.
+            trust_remote_code (`bool`, *optional*, defaults to `False`):
+                Whether or not to allow for custom models defined on the Hub in their own modeling files. This option
+                should only be set to `True` for repositories you trust and in which you have read the code, as it will
+                execute code present on the Hub on your local machine.
+            kwargs (additional keyword arguments, *optional*):
+                Will be passed to the Tokenizer `__init__` method. Can be used to set special tokens like `bos_token`,

+            max_target_length (`int`, *optional*):
+                Controls the maximum length of decoder inputs (target language texts or summaries) If left unset or set
+                to `None`, this will use the max_length value.
+            padding (`bool`, `str` or [`~utils.PaddingStrategy`], *optional*, defaults to `False`):
+                Activates and controls padding. Accepts the following values:
+
+                - `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single
+                  sequence if provided).
+                - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum
+                  acceptable input length for the model if that argument is not provided.
+                - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different
+                  lengths).
+            return_tensors (`str` or [`~utils.TensorType`], *optional*):
+                If set, will return tensors instead of list of python integers. Acceptable values are:
+
+                - `'tf'`: Return TensorFlow `tf.constant` objects.
+                - `'pt'`: Return PyTorch `torch.Tensor` objects.
+                - `'np'`: Return Numpy `np.ndarray` objects.
+            truncation (`bool`, `str` or [`~tokenization_utils_base.TruncationStrategy`], *optional*, defaults to `True`):
+                Activates and controls truncation. Accepts the following values:
+
+                - `True` or `'longest_first'`: Truncate to a maximum length specified with the argument `max_length` or
+                  to the maximum acceptable input length for the model if that argument is not provided. This will
+                  truncate token by token, removing a token from the longest sequence in the pair if a pair of
+                  sequences (or a batch of pairs) is provided.
+                - `'only_first'`: Truncate to a maximum length specified with the argument `max_length` or to the
+                  maximum acceptable input length for the model if that argument is not provided. This will only
+                  truncate the first sequence of a pair if a pair of sequences (or a batch of pairs) is provided.
+                - `'only_second'`: Truncate to a maximum length specified with the argument `max_length` or to the
+                  maximum acceptable input length for the model if that argument is not provided. This will only
+                  truncate the second sequence of a pair if a pair of sequences (or a batch of pairs) is provided.
+                - `False` or `'do_not_truncate'` (default): No truncation (i.e., can output batch with sequence lengths
+                  greater than the model maximum admissible input size).

+class Trainer:
+    """
+    Trainer is a simple but feature-complete training and eval loop for PyTorch, optimized for 🤗 Transformers.
+
+    Args:
+        model ([`PreTrainedModel`] or `torch.nn.Module`, *optional*):
+            The model to train, evaluate or use for predictions. If not provided, a `model_init` must be passed.
+
+            <Tip>
+
+            [`Trainer`] is optimized to work with the [`PreTrainedModel`] provided by the library. You can still use
+            your own models defined as `torch.nn.Module` as long as they work the same way as the 🤗 Transformers
+            models.
+
+            </Tip>
+
+        args ([`TrainingArguments`], *optional*):
+            The arguments to tweak for training. Will default to a basic instance of [`TrainingArguments`] with the
+            `output_dir` set to a directory named *tmp_trainer* in the current directory if not provided.
+        data_collator (`DataCollator`, *optional*):
+            The function to use to form a batch from a list of elements of `train_dataset` or `eval_dataset`. Will
+            default to [`default_data_collator`] if no `processing_class` is provided, an instance of
+            [`DataCollatorWithPadding`] otherwise if the processing_class is a feature extractor or tokenizer.
+        train_dataset (Union[`torch.utils.data.Dataset`, `torch.utils.data.IterableDataset`, `datasets.Dataset`], *optional*):
+            The dataset to use for training. If it is a [`~datasets.Dataset`], columns not accepted by the
+            `model.forward()` method are automatically removed.
+
+            Note that if it's a `torch.utils.data.IterableDataset` with some randomization and you are training in a
+            distributed fashion, your iterable dataset should either use a internal attribute `generator` that is a
+            `torch.Generator` for the randomization that must be identical on all processes (and the Trainer will
+            manually set the seed of this `generator` at each epoch) or have a `set_epoch()` method that internally
+            sets the seed of the RNGs used.
+        eval_dataset (Union[`torch.utils.data.Dataset`, Dict[str, `torch.utils.data.Dataset`, `datasets.Dataset`]), *optional*):
+             The dataset to use for evaluation. If it is a [`~datasets.Dataset`], columns not accepted by the
+             `model.forward()` method are automatically removed. If it is a dictionary, it will evaluate on each
+             dataset prepending the dictionary key to the metric name.
+        processing_class (`PreTrainedTokenizerBase` or `BaseImageProcessor` or `FeatureExtractionMixin` or `ProcessorMixin`, *optional*):
+            Processing class used to process the data. If provided, will be used to automatically process the inputs
+            for the model, and it will be saved along the model to make it easier to rerun an interrupted training or
+            reuse the fine-tuned model.
+            This supercedes the `tokenizer` argument, which is now deprecated.
+        model_init (`Callable[[], PreTrainedModel]`, *optional*):
+            A function that instantiates the model to be used. If provided, each call to [`~Trainer.train`] will start
+            from a new instance of the model as given by this function.
+
+            The function may have zero argument, or a single one containing the optuna/Ray Tune/SigOpt trial object, to
+            be able to choose different architectures according to hyper parameters (such as layer count, sizes of
+            inner layers, dropout probabilities etc).
+        compute_loss_func (`Callable`, *optional*):
+            A function that accepts the raw model outputs, labels, and the number of items in the entire accumulated
+            batch (batch_size * gradient_accumulation_steps) and returns the loss. For example, see the default [loss function](https://github.com/huggingface/transformers/blob/052e652d6d53c2b26ffde87e039b723949a53493/src/transformers/trainer.py#L3618) used by [`Trainer`].
+        compute_metrics (`Callable[[EvalPrediction], Dict]`, *optional*):
+            The function that will be used to compute metrics at evaluation. Must take a [`EvalPrediction`] and return
+            a dictionary string to metric values. *Note* When passing TrainingArgs with `batch_eval_metrics` set to
+            `True`, your compute_metrics function must take a boolean `compute_result` argument. This will be triggered
+            after the last eval batch to signal that the function needs to calculate and return the global summary
+            statistics rather than accumulating the batch-level statistics
+        callbacks (List of [`TrainerCallback`], *optional*):
+            A list of callbacks to customize the training loop. Will add those to the list of default callbacks
+            detailed in [here](callback).
+
+            If you want to remove one of the default callbacks used, use the [`Trainer.remove_callback`] method.
+        optimizers (`Tuple[torch.optim.Optimizer, torch.optim.lr_scheduler.LambdaLR]`, *optional*, defaults to `(None, None)`):
+            A tuple containing the optimizer and the scheduler to use. Will default to an instance of [`AdamW`] on your
+            model and a scheduler given by [`get_linear_schedule_with_warmup`] controlled by `args`.
+        optimizer_cls_and_kwargs (`Tuple[Type[torch.optim.Optimizer], Dict[str, Any]]`, *optional*):
+            A tuple containing the optimizer class and keyword arguments to use.
+            Overrides `optim` and `optim_args` in `args`. Incompatible with the `optimizers` argument.
+
+            Unlike `optimizers`, this argument avoids the need to place model parameters on the correct devices before initializing the Trainer.
+        preprocess_logits_for_metrics (`Callable[[torch.Tensor, torch.Tensor], torch.Tensor]`, *optional*):
+            A function that preprocess the logits right before caching them at each evaluation step. Must take two
+            tensors, the logits and the labels, and return the logits once processed as desired. The modifications made
+            by this function will be reflected in the predictions received by `compute_metrics`.
+
+            Note that the labels (second parameter) will be `None` if the dataset does not have them.
+
+    Important attributes:
+
+        - **model** -- Always points to the core model. If using a transformers model, it will be a [`PreTrainedModel`]
+          subclass.
+        - **model_wrapped** -- Always points to the most external model in case one or more other modules wrap the
+          original model. This is the model that should be used for the forward pass. For example, under `DeepSpeed`,
+          the inner model is wrapped in `DeepSpeed` and then again in `torch.nn.DistributedDataParallel`. If the inner
+          model hasn't been wrapped, then `self.model_wrapped` is the same as `self.model`.
+        - **is_model_parallel** -- Whether or not a model has been switched to a model parallel mode (different from
+          data parallelism, this means some of the model layers are split on different GPUs).
+        - **place_model_on_device** -- Whether or not to automatically place the model on the device - it will be set
+          to `False` if model parallel or deepspeed is used, or if the default
+          `TrainingArguments.place_model_on_device` is overridden to return `False` .
+        - **is_in_train** -- Whether or not a model is currently running `train` (e.g. when `evaluate` is called while
+          in `train`)

+
+    <Tip>
+
+    In all this class, one step is to be understood as one update step. When using gradient accumulation, one update
+    step may require several forward and backward passes: if you use `gradient_accumulation_steps=n`, then one update
+    step requires going through *n* batches.
+
+    </Tip>
+
+    Args:
+        epoch (`float`, *optional*):
+            Only set during training, will represent the epoch the training is at (the decimal part being the
+            percentage of the current epoch completed).
+        global_step (`int`, *optional*, defaults to 0):
+            During training, represents the number of update steps completed.
+        max_steps (`int`, *optional*, defaults to 0):
+            The number of update steps to do during the current training.
+        logging_steps (`int`, *optional*, defaults to 500):
+            Log every X updates steps
+        eval_steps (`int`, *optional*):

+            Save checkpoint every X updates steps.
+        train_batch_size (`int`, *optional*):
+            The batch size for the training dataloader. Only needed when
+            `auto_find_batch_size` has been used.
+        num_input_tokens_seen (`int`, *optional*, defaults to 0):
+            When tracking the inputs tokens, the number of tokens seen during training (number of input tokens, not the
+            number of prediction tokens).
+        total_flos (`float`, *optional*, defaults to 0):
+            The total number of floating operations done by the model since the beginning of training (stored as floats
+            to avoid overflow).
+        log_history (`List[Dict[str, float]]`, *optional*):
+            The list of logs done since the beginning of training.
+        best_metric (`float`, *optional*):

+            Whether or not this process is the local (e.g., on one machine if training in a distributed fashion on
+            several machines) main process.
+        is_world_process_zero (`bool`, *optional*, defaults to `True`):
+            Whether or not this process is the global main process (when training in a distributed fashion on several
+            machines, this is only going to be `True` for one process).
+        is_hyper_param_search (`bool`, *optional*, defaults to `False`):

+            impact the way data will be logged in TensorBoard.
+        stateful_callbacks (`List[StatefulTrainerCallback]`, *optional*):

+
+    Notes on memory reports:
+
+    In order to get memory usage report you need to install `psutil`. You can do that with `pip install psutil`.
+
+    Now when this method is run, you will see a report that will include: :
+
+    ```
+    init_mem_cpu_alloc_delta   =     1301MB
+    init_mem_cpu_peaked_delta  =      154MB
+    init_mem_gpu_alloc_delta   =      230MB
+    init_mem_gpu_peaked_delta  =        0MB
+    train_mem_cpu_alloc_delta  =     1345MB
+    train_mem_cpu_peaked_delta =        0MB
+    train_mem_gpu_alloc_delta  =      693MB
+    train_mem_gpu_peaked_delta =        7MB
+    ```
+
+    **Understanding the reports:**
+
+    - the first segment, e.g., `train__`, tells you which stage the metrics are for. Reports starting with `init_`
+        will be added to the first stage that gets run. So that if only evaluation is run, the memory usage for the
+        `__init__` will be reported along with the `eval_` metrics.
+    - the third segment, is either `cpu` or `gpu`, tells you whether it's the general RAM or the gpu0 memory
+        metric.
+    - `*_alloc_delta` - is the difference in the used/allocated memory counter between the end and the start of the
+        stage - it can be negative if a function released more memory than it allocated.
+    - `*_peaked_delta` - is any extra memory that was consumed and then freed - relative to the current allocated
+        memory counter - it is never negative. When you look at the metrics of any stage you add up `alloc_delta` +
+        `peaked_delta` and you know how much memory was needed to complete that stage.
+
+    The reporting happens only for process of rank 0 and gpu 0 (if there is a gpu). Typically this is enough since the
+    main process does the bulk of work, but it could be not quite so if model parallel is used and then other GPUs may
+    use a different amount of gpu memory. This is also not the same under DataParallel where gpu0 may require much more
+    memory than the rest since it stores the gradient and optimizer states for all participating GPUS. Perhaps in the
+    future these reports will evolve to measure those too.
+
+    The CPU RAM metric measures RSS (Resident Set Size) includes both the memory which is unique to the process and the
+    memory shared with other processes. It is important to note that it does not include swapped out memory, so the
+    reports could be imprecise.
+
+    The CPU peak memory is measured using a sampling thread. Due to python's GIL it may miss some of the peak memory if
+    that thread didn't get a chance to run when the highest memory was used. Therefore this report can be less than
+    reality. Using `tracemalloc` would have reported the exact peak memory, but it doesn't report memory allocations
+    outside of python. So if some C++ CUDA extension allocated its own memory it won't be reported. And therefore it
+    was dropped in favor of the memory sampling approach, which reads the current process memory usage.
+
+    The GPU allocated and peak memory reporting is done with `torch.cuda.memory_allocated()` and
+    `torch.cuda.max_memory_allocated()`. This metric reports only "deltas" for pytorch-specific allocations, as
+    `torch.cuda` memory management system doesn't track any memory allocated outside of pytorch. For example, the very
+    first cuda call typically loads CUDA kernels, which may take from 0.5 to 2GB of GPU memory.
+
+    Note that this tracker doesn't account for memory allocations outside of [`Trainer`]'s `__init__`, `train`,
+    `evaluate` and `predict` calls.
+
+    Because `evaluation` calls may happen during `train`, we can't handle nested invocations because
+    `torch.cuda.max_memory_allocated` is a single counter, so if it gets reset by a nested eval call, `train`'s tracker
+    will report incorrect info. If this [pytorch issue](https://github.com/pytorch/pytorch/issues/16266) gets resolved
+    it will be possible to change this class to be re-entrant. Until then we will only track the outer level of
+    `train`, `evaluate` and `predict` methods. Which means that if `eval` is called during `train`, it's the latter
+    that will account for its memory usage and that of the former.
+
+    This also means that if any other tool that is used along the [`Trainer`] calls
+    `torch.cuda.reset_peak_memory_stats`, the gpu peak memory stats could be invalid. And the [`Trainer`] will disrupt
+    the normal behavior of any such tools that rely on calling `torch.cuda.reset_peak_memory_stats` themselves.
+
+    For best performance you may want to consider turning the memory profiling off for production runs.

+@dataclass
+class TrainingArguments:
+    """
+    TrainingArguments is the subset of the arguments we use in our example scripts **which relate to the training loop
+    itself**.
+
+    Using [`HfArgumentParser`] we can turn this class into
+    [argparse](https://docs.python.org/3/library/argparse#module-argparse) arguments that can be specified on the
+    command line.
+
+    Parameters:
+        output_dir (`str`, *optional*, defaults to `"trainer_output"`):
+            The output directory where the model predictions and checkpoints will be written.
+        overwrite_output_dir (`bool`, *optional*, defaults to `False`):
+            If `True`, overwrite the content of the output directory. Use this to continue training if `output_dir`
+            points to a checkpoint directory.
+        do_train (`bool`, *optional*, defaults to `False`):
+            Whether to run training or not. This argument is not directly used by [`Trainer`], it's intended to be used
+            by your training/evaluation scripts instead. See the [example
+            scripts](https://github.com/huggingface/transformers/tree/main/examples) for more details.
+        do_eval (`bool`, *optional*):
+            Whether to run evaluation on the validation set or not. Will be set to `True` if `eval_strategy` is
+            different from `"no"`. This argument is not directly used by [`Trainer`], it's intended to be used by your
+            training/evaluation scripts instead. See the [example
+            scripts](https://github.com/huggingface/transformers/tree/main/examples) for more details.
+        do_predict (`bool`, *optional*, defaults to `False`):
+            Whether to run predictions on the test set or not. This argument is not directly used by [`Trainer`], it's
+            intended to be used by your training/evaluation scripts instead. See the [example
+            scripts](https://github.com/huggingface/transformers/tree/main/examples) for more details.
+        eval_strategy (`str` or [`~trainer_utils.IntervalStrategy`], *optional*, defaults to `"no"`):
+            The evaluation strategy to adopt during training. Possible values are:
+
+                - `"no"`: No evaluation is done during training.
+                - `"steps"`: Evaluation is done (and logged) every `eval_steps`.
+                - `"epoch"`: Evaluation is done at the end of each epoch.
+
+        prediction_loss_only (`bool`, *optional*, defaults to `False`):
+            When performing evaluation and generating predictions, only returns the loss.
+        per_device_train_batch_size (`int`, *optional*, defaults to 8):
+            The batch size per device accelerator core/CPU for training.
+        per_device_eval_batch_size (`int`, *optional*, defaults to 8):
+            The batch size per device accelerator core/CPU for evaluation.
+        gradient_accumulation_steps (`int`, *optional*, defaults to 1):
+            Number of updates steps to accumulate the gradients for, before performing a backward/update pass.
+
+            <Tip warning={true}>
+
+            When using gradient accumulation, one step is counted as one step with backward pass. Therefore, logging,
+            evaluation, save will be conducted every `gradient_accumulation_steps * xxx_step` training examples.
+
+            </Tip>
+
+        eval_accumulation_steps (`int`, *optional*):
+            Number of predictions steps to accumulate the output tensors for, before moving the results to the CPU. If
+            left unset, the whole predictions are accumulated on the device accelerator before being moved to the CPU (faster but
+            requires more memory).
+        eval_delay (`float`, *optional*):
+            Number of epochs or steps to wait for before the first evaluation can be performed, depending on the
+            eval_strategy.
+        torch_empty_cache_steps (`int`, *optional*):
+            Number of steps to wait before calling `torch.<device>.empty_cache()`. If left unset or set to None, cache will not be emptied.
+
+            <Tip>
+
+            This can help avoid CUDA out-of-memory errors by lowering peak VRAM usage at a cost of about [10% slower performance](https://github.com/huggingface/transformers/issues/31372).
+
+            </Tip>
+
+        learning_rate (`float`, *optional*, defaults to 5e-5):
+            The initial learning rate for [`AdamW`] optimizer.
+        weight_decay (`float`, *optional*, defaults to 0):
+            The weight decay to apply (if not zero) to all layers except all bias and LayerNorm weights in [`AdamW`]
+            optimizer.
+        adam_beta1 (`float`, *optional*, defaults to 0.9):
+            The beta1 hyperparameter for the [`AdamW`] optimizer.
+        adam_beta2 (`float`, *optional*, defaults to 0.999):
+            The beta2 hyperparameter for the [`AdamW`] optimizer.
+        adam_epsilon (`float`, *optional*, defaults to 1e-8):
+            The epsilon hyperparameter for the [`AdamW`] optimizer.
+        max_grad_norm (`float`, *optional*, defaults to 1.0):
+            Maximum gradient norm (for gradient clipping).
+        num_train_epochs(`float`, *optional*, defaults to 3.0):
+            Total number of training epochs to perform (if not an integer, will perform the decimal part percents of
+            the last epoch before stopping training).
+        max_steps (`int`, *optional*, defaults to -1):
+            If set to a positive number, the total number of training steps to perform. Overrides `num_train_epochs`.
+            For a finite dataset, training is reiterated through the dataset (if all data is exhausted) until
+            `max_steps` is reached.
+        lr_scheduler_type (`str` or [`SchedulerType`], *optional*, defaults to `"linear"`):
+            The scheduler type to use. See the documentation of [`SchedulerType`] for all possible values.
+        lr_scheduler_kwargs ('dict', *optional*, defaults to {}):
+            The extra arguments for the lr_scheduler. See the documentation of each scheduler for possible values.
+        warmup_ratio (`float`, *optional*, defaults to 0.0):
+            Ratio of total training steps used for a linear warmup from 0 to `learning_rate`.
+        warmup_steps (`int`, *optional*, defaults to 0):
+            Number of steps used for a linear warmup from 0 to `learning_rate`. Overrides any effect of `warmup_ratio`.
+        log_level (`str`, *optional*, defaults to `passive`):
+            Logger log level to use on the main process. Possible choices are the log levels as strings: 'debug',
+            'info', 'warning', 'error' and 'critical', plus a 'passive' level which doesn't set anything and keeps the
+            current log level for the Transformers library (which will be `"warning"` by default).
+        log_level_replica (`str`, *optional*, defaults to `"warning"`):
+            Logger log level to use on replicas. Same choices as `log_level`"
+        log_on_each_node (`bool`, *optional*, defaults to `True`):
+            In multinode distributed training, whether to log using `log_level` once per node, or only on the main
+            node.
+        logging_dir (`str`, *optional*):
+            [TensorBoard](https://www.tensorflow.org/tensorboard) log directory. Will default to
+            *output_dir/runs/**CURRENT_DATETIME_HOSTNAME***.
+        logging_strategy (`str` or [`~trainer_utils.IntervalStrategy`], *optional*, defaults to `"steps"`):
+            The logging strategy to adopt during training. Possible values are:
+
+                - `"no"`: No logging is done during training.
+                - `"epoch"`: Logging is done at the end of each epoch.
+                - `"steps"`: Logging is done every `logging_steps`.
+
+        logging_first_step (`bool`, *optional*, defaults to `False`):
+            Whether to log the first `global_step` or not.
+        logging_steps (`int` or `float`, *optional*, defaults to 500):
+            Number of update steps between two logs if `logging_strategy="steps"`. Should be an integer or a float in
+            range `[0,1)`. If smaller than 1, will be interpreted as ratio of total training steps.
+        logging_nan_inf_filter (`bool`, *optional*, defaults to `True`):
+            Whether to filter `nan` and `inf` losses for logging. If set to `True` the loss of every step that is `nan`
+            or `inf` is filtered and the average loss of the current logging window is taken instead.
+
+            <Tip>
+
+            `logging_nan_inf_filter` only influences the logging of loss values, it does not change the behavior the
+            gradient is computed or applied to the model.
+
+            </Tip>
+
+        save_strategy (`str` or [`~trainer_utils.SaveStrategy`], *optional*, defaults to `"steps"`):
+            The checkpoint save strategy to adopt during training. Possible values are:
+
+                - `"no"`: No save is done during training.
+                - `"epoch"`: Save is done at the end of each epoch.
+                - `"steps"`: Save is done every `save_steps`.
+                - `"best"`: Save is done whenever a new `best_metric` is achieved.
+
+                If `"epoch"` or `"steps"` is chosen, saving will also be performed at the
+                very end of training, always.
+        save_steps (`int` or `float`, *optional*, defaults to 500):
+            Number of updates steps before two checkpoint saves if `save_strategy="steps"`. Should be an integer or a
+            float in range `[0,1)`. If smaller than 1, will be interpreted as ratio of total training steps.
+        save_total_limit (`int`, *optional*):
+            If a value is passed, will limit the total amount of checkpoints. Deletes the older checkpoints in
+            `output_dir`. When `load_best_model_at_end` is enabled, the "best" checkpoint according to
+            `metric_for_best_model` will always be retained in addition to the most recent ones. For example, for
+            `save_total_limit=5` and `load_best_model_at_end`, the four last checkpoints will always be retained
+            alongside the best model. When `save_total_limit=1` and `load_best_model_at_end`, it is possible that two
+            checkpoints are saved: the last one and the best one (if they are different).
+        save_safetensors (`bool`, *optional*, defaults to `True`):
+            Use [safetensors](https://huggingface.co/docs/safetensors) saving and loading for state dicts instead of
+            default `torch.load` and `torch.save`.
+        save_on_each_node (`bool`, *optional*, defaults to `False`):
+            When doing multi-node distributed training, whether to save models and checkpoints on each node, or only on
+            the main one.
+
+            This should not be activated when the different nodes use the same storage as the files will be saved with
+            the same names for each node.
+        save_only_model (`bool`, *optional*, defaults to `False`):
+            When checkpointing, whether to only save the model, or also the optimizer, scheduler & rng state.
+            Note that when this is true, you won't be able to resume training from checkpoint.
+            This enables you to save storage by not storing the optimizer, scheduler & rng state.

+        use_cpu (`bool`, *optional*, defaults to `False`):
+            Whether or not to use cpu. If set to False, we will use cuda or mps device if available.
+        seed (`int`, *optional*, defaults to 42):
+            Random seed that will be set at the beginning of training. To ensure reproducibility across runs, use the

+        data_seed (`int`, *optional*):
+            Random seed to be used with data samplers. If not set, random generators for data sampling will use the
+            same seed as `seed`. This can be used to ensure reproducibility of data sampling, independent of the model
+            seed.
+        jit_mode_eval (`bool`, *optional*, defaults to `False`):
+            Whether or not to use PyTorch jit trace for inference.
+        use_ipex (`bool`, *optional*, defaults to `False`):

+        half_precision_backend (`str`, *optional*, defaults to `"auto"`):
+            The backend to use for mixed precision training. Must be one of `"auto", "apex", "cpu_amp"`. `"auto"` will
+            use CPU/CUDA AMP or APEX depending on the PyTorch version detected, while the other choices will force the
+            requested backend.
+        bf16_full_eval (`bool`, *optional*, defaults to `False`):
+            Whether to use full bfloat16 evaluation instead of 32-bit. This will be faster and save memory but can harm
+            metric values. This is an experimental API and it may change.
+        fp16_full_eval (`bool`, *optional*, defaults to `False`):
+            Whether to use full float16 evaluation instead of 32-bit. This will be faster and save memory but can harm
+            metric values.
+        tf32 (`bool`, *optional*):
+            Whether to enable the TF32 mode, available in Ampere and newer GPU architectures. The default value depends
+            on PyTorch's version default of `torch.backends.cuda.matmul.allow_tf32`. For more details please refer to
+            the [TF32](https://huggingface.co/docs/transformers/perf_train_gpu_one#tf32) documentation. This is an
+            experimental API and it may change.

+        eval_steps (`int` or `float`, *optional*):
+            Number of update steps between two evaluations if `eval_strategy="steps"`. Will default to the same
+            value as `logging_steps` if not set. Should be an integer or a float in range `[0,1)`. If smaller than 1,
+            will be interpreted as ratio of total training steps.
+        dataloader_num_workers (`int`, *optional*, defaults to 0):
+            Number of subprocesses to use for data loading (PyTorch only). 0 means that the data will be loaded in the
+            main process.
+        past_index (`int`, *optional*, defaults to -1):
+            Some models like [TransformerXL](../model_doc/transformerxl) or [XLNet](../model_doc/xlnet) can make use of
+            the past hidden states for their predictions. If this argument is set to a positive int, the `Trainer` will
+            use the corresponding output (usually index 2) as the past state and feed it to the model at the next
+            training step under the keyword argument `mems`.
+        run_name (`str`, *optional*, defaults to `output_dir`):
+            A descriptor for the run. Typically used for [wandb](https://www.wandb.com/),
+            [mlflow](https://www.mlflow.org/), [comet](https://www.comet.com/site) and [swanlab](https://swanlab.cn)
+            logging. If not specified, will be the same as `output_dir`.
+        disable_tqdm (`bool`, *optional*):
+            Whether or not to disable the tqdm progress bars and table of metrics produced by
+            [`~notebook.NotebookTrainingTracker`] in Jupyter Notebooks. Will default to `True` if the logging level is
+            set to warn or lower (default), `False` otherwise.
+        remove_unused_columns (`bool`, *optional*, defaults to `True`):
+            Whether or not to automatically remove the columns unused by the model forward method.
+        label_names (`List[str]`, *optional*):
+            The list of keys in your dictionary of inputs that correspond to the labels.
+
+            Will eventually default to the list of argument names accepted by the model that contain the word "label",
+            except if the model used is one of the `XxxForQuestionAnswering` in which case it will also include the
+            `["start_positions", "end_positions"]` keys.
+        load_best_model_at_end (`bool`, *optional*, defaults to `False`):
+            Whether or not to load the best model found during training at the end of training. When this option is
+            enabled, the best checkpoint will always be saved. See
+            [`save_total_limit`](https://huggingface.co/docs/transformers/main_classes/trainer#transformers.TrainingArguments.save_total_limit)
+            for more.
+
+            <Tip>
+
+            When set to `True`, the parameters `save_strategy` needs to be the same as `eval_strategy`, and in
+            the case it is "steps", `save_steps` must be a round multiple of `eval_steps`.
+
+            </Tip>
+
+        metric_for_best_model (`str`, *optional*):
+            Use in conjunction with `load_best_model_at_end` to specify the metric to use to compare two different
+            models. Must be the name of a metric returned by the evaluation with or without the prefix `"eval_"`.
+
+            If not specified, this will default to `"loss"` when either `load_best_model_at_end == True`
+            or `lr_scheduler_type == SchedulerType.REDUCE_ON_PLATEAU` (to use the evaluation loss).
+
+            If you set this value, `greater_is_better` will default to `True` unless the name ends with "loss".
+            Don't forget to set it to `False` if your metric is better when lower.
+        greater_is_better (`bool`, *optional*):
+            Use in conjunction with `load_best_model_at_end` and `metric_for_best_model` to specify if better models
+            should have a greater metric or not. Will default to:
+
+            - `True` if `metric_for_best_model` is set to a value that doesn't end in `"loss"`.
+            - `False` if `metric_for_best_model` is not set, or set to a value that ends in `"loss"`.
+        ignore_data_skip (`bool`, *optional*, defaults to `False`):
+            When resuming training, whether or not to skip the epochs and batches to get the data loading at the same
+            stage as in the previous training. If set to `True`, the training will begin faster (as that skipping step
+            can take a long time) but will not yield the same results as the interrupted training would have.
+        fsdp (`bool`, `str` or list of [`~trainer_utils.FSDPOption`], *optional*, defaults to `''`):
+            Use PyTorch Distributed Parallel Training (in distributed training only).

+            - `"offload"`: Offload parameters and gradients to CPUs (only compatible with `"full_shard"` and
+              `"shard_grad_op"`).
+            - `"auto_wrap"`: Automatically recursively wrap layers with FSDP using `default_auto_wrap_policy`.
+        fsdp_config (`str` or `dict`, *optional*):
+            Config to be used with fsdp (Pytorch Distributed Parallel Training). The value is either a location of
+            fsdp json config file (e.g., `fsdp_config.json`) or an already loaded json file as `dict`.
+
+            A List of config and its options:
+                - min_num_params (`int`, *optional*, defaults to `0`):
+                    FSDP's minimum number of parameters for Default Auto Wrapping. (useful only when `fsdp` field is
+                    passed).
+                - transformer_layer_cls_to_wrap (`List[str]`, *optional*):
+                    List of transformer layer class names (case-sensitive) to wrap, e.g, `BertLayer`, `GPTJBlock`,
+                    `T5Block` .... (useful only when `fsdp` flag is passed).
+                - backward_prefetch (`str`, *optional*)
+                    FSDP's backward prefetch mode. Controls when to prefetch next set of parameters (useful only when
+                    `fsdp` field is passed).
+
+                    A list of options along the following:
+
+                    - `"backward_pre"` : Prefetches the next set of parameters before the current set of parameter's
+                      gradient
+                        computation.
+                    - `"backward_post"` : This prefetches the next set of parameters after the current set of
+                      parameter’s
+                        gradient computation.
+                - forward_prefetch (`bool`, *optional*, defaults to `False`)
+                    FSDP's forward prefetch mode (useful only when `fsdp` field is passed).
+                     If `"True"`, then FSDP explicitly prefetches the next upcoming all-gather while executing in the
+                     forward pass.
+                - limit_all_gathers (`bool`, *optional*, defaults to `False`)
+                    FSDP's limit_all_gathers (useful only when `fsdp` field is passed).

+                     all-gathers.
+                - use_orig_params (`bool`, *optional*, defaults to `True`)
+                    If `"True"`, allows non-uniform `requires_grad` during init, which means support for interspersed
+                    frozen and trainable parameters. Useful in cases such as parameter-efficient fine-tuning. Please
+                    refer this
+                    [blog](https://dev-discuss.pytorch.org/t/rethinking-pytorch-fully-sharded-data-parallel-fsdp-from-first-principles/1019
+                - sync_module_states (`bool`, *optional*, defaults to `True`)
+                    If `"True"`, each individually wrapped FSDP unit will broadcast module parameters from rank 0 to
+                    ensure they are the same across all ranks after initialization
+                - cpu_ram_efficient_loading (`bool`, *optional*, defaults to `False`)
+                    If `"True"`, only the first process loads the pretrained model checkpoint while all other processes
+                    have empty weights.  When this setting as `"True"`, `sync_module_states` also must to be `"True"`,
+                    otherwise all the processes except the main process would have random weights leading to unexpected
+                    behaviour during training.
+                - activation_checkpointing (`bool`, *optional*, defaults to `False`):
+                    If `"True"`, activation checkpointing is a technique to reduce memory usage by clearing activations of
+                    certain layers and recomputing them during a backward pass. Effectively, this trades extra
+                    computation time for reduced memory usage.
+                - xla (`bool`, *optional*, defaults to `False`):
+                    Whether to use PyTorch/XLA Fully Sharded Data Parallel Training. This is an experimental feature
+                    and its API may evolve in the future.
+                - xla_fsdp_settings (`dict`, *optional*)
+                    The value is a dictionary which stores the XLA FSDP wrapping parameters.
+
+                    For a complete list of options, please see [here](
+                    https://github.com/pytorch/xla/blob/master/torch_xla/distributed/fsdp/xla_fully_sharded_data_parallel.py).
+                - xla_fsdp_grad_ckpt (`bool`, *optional*, defaults to `False`):
+                    Will use gradient checkpointing over each nested XLA FSDP wrapped layer. This setting can only be
+                    used when the xla flag is set to true, and an auto wrapping policy is specified through
+                    fsdp_min_num_params or fsdp_transformer_layer_cls_to_wrap.
+        tp_size (`int`, *optional*):
+            Use tp_size to enable PyTorch tensor parallelism. Tensor parallelism support is only available to models having `base_tp_plan`
+            in their respective config classes.
+            Set a value greater than 1 to activate TP. The same is used to prepare device mesh internally. Requires accelerate>1.3.0.
+        deepspeed (`str` or `dict`, *optional*):
+            Use [Deepspeed](https://github.com/deepspeedai/DeepSpeed). This is an experimental feature and its API may
+            evolve in the future. The value is either the location of DeepSpeed json config file (e.g.,
+            `ds_config.json`) or an already loaded json file as a `dict`"
+
+            <Tip warning={true}>
+                If enabling any Zero-init, make sure that your model is not initialized until
+                *after* initializing the `TrainingArguments`, else it will not be applied.
+            </Tip>
+
+        accelerator_config (`str`, `dict`, or `AcceleratorConfig`, *optional*):
+            Config to be used with the internal `Accelerator` implementation. The value is either a location of
+            accelerator json config file (e.g., `accelerator_config.json`), an already loaded json file as `dict`,
+            or an instance of [`~trainer_pt_utils.AcceleratorConfig`].
+
+            A list of config and its options:
+                - split_batches (`bool`, *optional*, defaults to `False`):
+                    Whether or not the accelerator should split the batches yielded by the dataloaders across the devices. If
+                    `True` the actual batch size used will be the same on any kind of distributed processes, but it must be a
+                    round multiple of the `num_processes` you are using. If `False`, actual batch size used will be the one set
+                    in your script multiplied by the number of processes.
+                - dispatch_batches (`bool`, *optional*):
+                    If set to `True`, the dataloader prepared by the Accelerator is only iterated through on the main process
+                    and then the batches are split and broadcast to each process. Will default to `True` for `DataLoader` whose
+                    underlying dataset is an `IterableDataset`, `False` otherwise.
+                - even_batches (`bool`, *optional*, defaults to `True`):
+                    If set to `True`, in cases where the total batch size across all processes does not exactly divide the
+                    dataset, samples at the start of the dataset will be duplicated so the batch can be divided equally among
+                    all workers.
+                - use_seedable_sampler (`bool`, *optional*, defaults to `True`):
+                    Whether or not use a fully seedable random sampler ([`accelerate.data_loader.SeedableRandomSampler`]). Ensures
+                    training results are fully reproducible using a different sampling technique. While seed-to-seed results
+                    may differ, on average the differences are negligible when using multiple different seeds to compare. Should
+                    also be ran with [`~utils.set_seed`] for the best results.
+                - use_configured_state (`bool`, *optional*, defaults to `False`):
+                    Whether or not to use a pre-configured `AcceleratorState` or `PartialState` defined before calling `TrainingArguments`.
+                    If `True`, an `Accelerator` or `PartialState` must be initialized. Note that by doing so, this could lead to issues
+                    with hyperparameter tuning.
+
+        label_smoothing_factor (`float`, *optional*, defaults to 0.0):
+            The label smoothing factor to use. Zero means no label smoothing, otherwise the underlying onehot-encoded
+            labels are changed from 0s and 1s to `label_smoothing_factor/num_labels` and `1 - label_smoothing_factor +
+            label_smoothing_factor/num_labels` respectively.
+        debug (`str` or list of [`~debug_utils.DebugOption`], *optional*, defaults to `""`):
+            Enable one or more debug features. This is an experimental feature.
+
+            Possible options are:
+
+            - `"underflow_overflow"`: detects overflow in model's input/outputs and reports the last frames that led to
+              the event
+            - `"tpu_metrics_debug"`: print debug metrics on TPU
+
+            The options should be separated by whitespaces.
+        optim (`str` or [`training_args.OptimizerNames`], *optional*, defaults to `"adamw_torch"`):
+            The optimizer to use, such as "adamw_hf", "adamw_torch", "adamw_torch_fused", "adamw_apex_fused", "adamw_anyprecision",
+            "adafactor". See `OptimizerNames` in [training_args.py](https://github.com/huggingface/transformers/blob/main/src/transformers/training_args.py)
+            for a full list of optimizers.
+        optim_args (`str`, *optional*):
+            Optional arguments that are supplied to optimizers such as AnyPrecisionAdamW, AdEMAMix, and GaLore.
+        group_by_length (`bool`, *optional*, defaults to `False`):
+            Whether or not to group together samples of roughly the same length in the training dataset (to minimize
+            padding applied and be more efficient). Only useful if applying dynamic padding.
+        length_column_name (`str`, *optional*, defaults to `"length"`):
+            Column name for precomputed lengths. If the column exists, grouping by length will use these values rather
+            than computing them on train startup. Ignored unless `group_by_length` is `True` and the dataset is an
+            instance of `Dataset`.
+        report_to (`str` or `List[str]`, *optional*, defaults to `"all"`):
+            The list of integrations to report the results and logs to. Supported platforms are `"azure_ml"`,
+            `"clearml"`, `"codecarbon"`, `"comet_ml"`, `"dagshub"`, `"dvclive"`, `"flyte"`, `"mlflow"`, `"neptune"`,
+            `"swanlab"`, `"tensorboard"`, and `"wandb"`. Use `"all"` to report to all integrations installed, `"none"`
+            for no integrations.
+        ddp_find_unused_parameters (`bool`, *optional*):
+            When using distributed training, the value of the flag `find_unused_parameters` passed to
+            `DistributedDataParallel`. Will default to `False` if gradient checkpointing is used, `True` otherwise.
+        ddp_bucket_cap_mb (`int`, *optional*):
+            When using distributed training, the value of the flag `bucket_cap_mb` passed to `DistributedDataParallel`.
+        ddp_broadcast_buffers (`bool`, *optional*):
+            When using distributed training, the value of the flag `broadcast_buffers` passed to
+            `DistributedDataParallel`. Will default to `False` if gradient checkpointing is used, `True` otherwise.
+        dataloader_pin_memory (`bool`, *optional*, defaults to `True`):
+            Whether you want to pin memory in data loaders or not. Will default to `True`.
+        dataloader_persistent_workers (`bool`, *optional*, defaults to `False`):
+            If True, the data loader will not shut down the worker processes after a dataset has been consumed once.
+            This allows to maintain the workers Dataset instances alive. Can potentially speed up training, but will
+            increase RAM usage. Will default to `False`.
+        dataloader_prefetch_factor (`int`, *optional*):
+            Number of batches loaded in advance by each worker.
+            2 means there will be a total of 2 * num_workers batches prefetched across all workers.
+        skip_memory_metrics (`bool`, *optional*, defaults to `True`):
+            Whether to skip adding of memory profiler reports to metrics. This is skipped by default because it slows
+            down the training and evaluation speed.
+        push_to_hub (`bool`, *optional*, defaults to `False`):
+            Whether or not to push the model to the Hub every time the model is saved. If this is activated,
+            `output_dir` will begin a git directory synced with the repo (determined by `hub_model_id`) and the content
+            will be pushed each time a save is triggered (depending on your `save_strategy`). Calling
+            [`~Trainer.save_model`] will also trigger a push.
+
+            <Tip warning={true}>
+
+            If `output_dir` exists, it needs to be a local clone of the repository to which the [`Trainer`] will be
+            pushed.
+
+            </Tip>
+
+        resume_from_checkpoint (`str`, *optional*):
+            The path to a folder with a valid checkpoint for your model. This argument is not directly used by
+            [`Trainer`], it's intended to be used by your training/evaluation scripts instead. See the [example
+            scripts](https://github.com/huggingface/transformers/tree/main/examples) for more details.
+        hub_model_id (`str`, *optional*):
+            The name of the repository to keep in sync with the local *output_dir*. It can be a simple model ID in
+            which case the model will be pushed in your namespace. Otherwise it should be the whole repository name,
+            for instance `"user_name/model"`, which allows you to push to an organization you are a member of with
+            `"organization_name/model"`. Will default to `user_name/output_dir_name` with *output_dir_name* being the
+            name of `output_dir`.
+
+            Will default to the name of `output_dir`.
+        hub_strategy (`str` or [`~trainer_utils.HubStrategy`], *optional*, defaults to `"every_save"`):
+            Defines the scope of what is pushed to the Hub and when. Possible values are:
+
+            - `"end"`: push the model, its configuration, the processing class e.g. tokenizer (if passed along to the [`Trainer`]) and a
+              draft of a model card when the [`~Trainer.save_model`] method is called.
+            - `"every_save"`: push the model, its configuration, the processing class e.g. tokenizer (if passed along to the [`Trainer`]) and
+              a draft of a model card each time there is a model save. The pushes are asynchronous to not block
+              training, and in case the save are very frequent, a new push is only attempted if the previous one is
+              finished. A last push is made with the final model at the end of training.
+            - `"checkpoint"`: like `"every_save"` but the latest checkpoint is also pushed in a subfolder named
+              last-checkpoint, allowing you to resume training easily with
+              `trainer.train(resume_from_checkpoint="last-checkpoint")`.
+            - `"all_checkpoints"`: like `"checkpoint"` but all checkpoints are pushed like they appear in the output
+              folder (so you will get one checkpoint folder per folder in your final repository)
+
+        hub_token (`str`, *optional*):
+            The token to use to push the model to the Hub. Will default to the token in the cache folder obtained with
+            `huggingface-cli login`.
+        hub_private_repo (`bool`, *optional*):
+            Whether to make the repo private. If `None` (default), the repo will be public unless the organization's default is private. This value is ignored if the repo already exists.
+        hub_always_push (`bool`, *optional*, defaults to `False`):
+            Unless this is `True`, the `Trainer` will skip pushing a checkpoint when the previous push is not finished.
+        gradient_checkpointing (`bool`, *optional*, defaults to `False`):
+            If True, use gradient checkpointing to save memory at the expense of slower backward pass.
+        gradient_checkpointing_kwargs (`dict`, *optional*, defaults to `None`):
+            Key word arguments to be passed to the `gradient_checkpointing_enable` method.
+        include_inputs_for_metrics (`bool`, *optional*, defaults to `False`):
+            This argument is deprecated. Use `include_for_metrics` instead, e.g, `include_for_metrics = ["inputs"]`.
+        include_for_metrics (`List[str]`, *optional*, defaults to `[]`):
+            Include additional data in the `compute_metrics` function if needed for metrics computation.
+            Possible options to add to `include_for_metrics` list:
+            - `"inputs"`: Input data passed to the model, intended for calculating input dependent metrics.
+            - `"loss"`: Loss values computed during evaluation, intended for calculating loss dependent metrics.
+        eval_do_concat_batches (`bool`, *optional*, defaults to `True`):
+            Whether to recursively concat inputs/losses/labels/predictions across batches. If `False`,
+            will instead store them as lists, with each batch kept separate.
+        auto_find_batch_size (`bool`, *optional*, defaults to `False`)
+            Whether to find a batch size that will fit into memory automatically through exponential decay, avoiding
+            CUDA Out-of-Memory errors. Requires accelerate to be installed (`pip install accelerate`)
+        full_determinism (`bool`, *optional*, defaults to `False`)
+            If `True`, [`enable_full_determinism`] is called instead of [`set_seed`] to ensure reproducible results in
+            distributed training. Important: this will negatively impact the performance, so only use it for debugging.
+        torchdynamo (`str`, *optional*):
+            If set, the backend compiler for TorchDynamo. Possible choices are `"eager"`, `"aot_eager"`, `"inductor"`,
+            `"nvfuser"`, `"aot_nvfuser"`, `"aot_cudagraphs"`, `"ofi"`, `"fx2trt"`, `"onnxrt"` and `"ipex"`.
+        ray_scope (`str`, *optional*, defaults to `"last"`):
+            The scope to use when doing hyperparameter search with Ray. By default, `"last"` will be used. Ray will
+            then use the last checkpoint of all trials, compare those, and select the best one. However, other options
+            are also available. See the [Ray documentation](
+            https://docs.ray.io/en/latest/tune/api_docs/analysis.html#ray.tune.ExperimentAnalysis.get_best_trial) for
+            more options.
+        ddp_timeout (`int`, *optional*, defaults to 1800):
+            The timeout for `torch.distributed.init_process_group` calls, used to avoid GPU socket timeouts when
+            performing slow operations in distributed runnings. Please refer the [PyTorch documentation]
+            (https://pytorch.org/docs/stable/distributed.html#torch.distributed.init_process_group) for more
+            information.
+        use_mps_device (`bool`, *optional*, defaults to `False`):
+            This argument is deprecated.`mps` device will be used if it is available similar to `cuda` device.
+        torch_compile (`bool`, *optional*, defaults to `False`):
+            Whether or not to compile the model using PyTorch 2.0
+            [`torch.compile`](https://pytorch.org/get-started/pytorch-2.0/).
+
+            This will use the best defaults for the [`torch.compile`
+            API](https://pytorch.org/docs/stable/generated/torch.compile.html?highlight=torch+compile#torch.compile).
+            You can customize the defaults with the argument `torch_compile_backend` and `torch_compile_mode` but we
+            don't guarantee any of them will work as the support is progressively rolled in in PyTorch.
+
+            This flag and the whole compile API is experimental and subject to change in future releases.
+        torch_compile_backend (`str`, *optional*):
+            The backend to use in `torch.compile`. If set to any value, `torch_compile` will be set to `True`.
+
+            Refer to the PyTorch doc for possible values and note that they may change across PyTorch versions.
+
+            This flag is experimental and subject to change in future releases.
+        torch_compile_mode (`str`, *optional*):
+            The mode to use in `torch.compile`. If set to any value, `torch_compile` will be set to `True`.
+
+            Refer to the PyTorch doc for possible values and note that they may change across PyTorch versions.
+
+            This flag is experimental and subject to change in future releases.
+        split_batches (`bool`, *optional*):
+            Whether or not the accelerator should split the batches yielded by the dataloaders across the devices
+            during distributed training. If
+
+            set to `True`, the actual batch size used will be the same on any kind of distributed processes, but it
+            must be a
+
+            round multiple of the number of processes you are using (such as GPUs).
+        include_tokens_per_second (`bool`, *optional*):
+            Whether or not to compute the number of tokens per second per device for training speed metrics.
+
+            This will iterate over the entire training dataloader once beforehand,
+
+            and will slow down the entire process.
+
+        include_num_input_tokens_seen (`bool`, *optional*):
+            Whether or not to track the number of input tokens seen throughout training.
+
+            May be slower in distributed training as gather operations must be called.
+
+        neftune_noise_alpha (`Optional[float]`):
+            If not `None`, this will activate NEFTune noise embeddings. This can drastically improve model performance
+            for instruction fine-tuning. Check out the [original paper](https://arxiv.org/abs/2310.05914) and the
+            [original code](https://github.com/neelsjain/NEFTune). Support transformers `PreTrainedModel` and also
+            `PeftModel` from peft. The original paper used values in the range [5.0, 15.0].
+        optim_target_modules (`Union[str, List[str]]`, *optional*):
+            The target modules to optimize, i.e. the module names that you would like to train.
+            Currently used for the GaLore algorithm (https://arxiv.org/abs/2403.03507) and APOLLO algorithm (https://arxiv.org/abs/2412.05270).
+            See GaLore implementation (https://github.com/jiaweizzhao/GaLore) and APOLLO implementation (https://github.com/zhuhanqing/APOLLO) for more details.
+            You need to make sure to pass a valid GaLore or APOLLO optimizer, e.g., one of: "apollo_adamw", "galore_adamw", "galore_adamw_8bit", "galore_adafactor" and make sure that the target modules are `nn.Linear` modules only.
+
+        batch_eval_metrics (`Optional[bool]`, defaults to `False`):
+            If set to `True`, evaluation will call compute_metrics at the end of each batch to accumulate statistics
+            rather than saving all eval logits in memory. When set to `True`, you must pass a compute_metrics function
+            that takes a boolean argument `compute_result`, which when passed `True`, will trigger the final global
+            summary statistics from the batch-level summary statistics you've accumulated over the evaluation set.
+
+        eval_on_start (`bool`, *optional*, defaults to `False`):
+            Whether to perform a evaluation step (sanity check) before the training to ensure the validation steps works correctly.
+
+        eval_use_gather_object (`bool`, *optional*, defaults to `False`):
+            Whether to run recursively gather object in a nested list/tuple/dictionary of objects from all devices. This should only be enabled if users are not just returning tensors, and this is actively discouraged by PyTorch.
+
+        use_liger_kernel (`bool`, *optional*, defaults to `False`):
+            Whether enable [Liger](https://github.com/linkedin/Liger-Kernel) Kernel for LLM model training.
+            It can effectively increase multi-GPU training throughput by ~20% and reduces memory usage by ~60%, works out of the box with
+            flash attention, PyTorch FSDP, and Microsoft DeepSpeed. Currently, it supports llama, mistral, mixtral and gemma models.
+
+        average_tokens_across_devices (`bool`, *optional*, defaults to `False`):
+            Whether or not to average tokens across devices. If enabled, will use all_reduce to synchronize
+            num_tokens_in_batch for precise loss calculation. Reference:
+            https://github.com/huggingface/transformers/issues/34242

+    TrainingArguments is the subset of the arguments we use in our example scripts **which relate to the training loop
+    itself**.
+
+    Using [`HfArgumentParser`] we can turn this class into
+    [argparse](https://docs.python.org/3/library/argparse#module-argparse) arguments that can be specified on the
+    command line.
+
+    Parameters:
+        output_dir (`str`):
+            The output directory where the model predictions and checkpoints will be written.
+        overwrite_output_dir (`bool`, *optional*, defaults to `False`):

+            points to a checkpoint directory.
+        do_train (`bool`, *optional*, defaults to `False`):
+            Whether to run training or not. This argument is not directly used by [`Trainer`], it's intended to be used
+            by your training/evaluation scripts instead. See the [example
+            scripts](https://github.com/huggingface/transformers/tree/main/examples) for more details.
+        do_eval (`bool`, *optional*):
+            Whether to run evaluation on the validation set or not. Will be set to `True` if `eval_strategy` is
+            different from `"no"`. This argument is not directly used by [`Trainer`], it's intended to be used by your
+            training/evaluation scripts instead. See the [example
+            scripts](https://github.com/huggingface/transformers/tree/main/examples) for more details.
+        do_predict (`bool`, *optional*, defaults to `False`):

+            evaluation, save will be conducted every `gradient_accumulation_steps * xxx_step` training examples.
+
+            </Tip>

+            `max_steps` is reached.
+        warmup_ratio (`float`, *optional*, defaults to 0.0):
+            Ratio of total training steps used for a linear warmup from 0 to `learning_rate`.
+        warmup_steps (`int`, *optional*, defaults to 0):

+
+    Although it is not required, a `Returns` block can also be added, which will be included in the schema. This is

+
+    Args:
+        func: The function to generate a JSON schema for.
+
+    Returns:
+        A dictionary containing the JSON schema for the function.

+    >>>    A function that multiplies two numbers
+    >>>
+    >>>    Args:

+
+    The general use for these schemas is that they are used to generate tool descriptions for chat templates that
+    support them, like so:
+
+    ```python
+    >>> from transformers import AutoTokenizer
+    >>> from transformers.utils import get_json_schema
+    >>>
+    >>> def multiply(x: float, y: float):
+    >>>    '''

+    >>>
+    >>>    Args:
+    >>>        x: The first number to multiply
+    >>>        y: The second number to multiply
+    >>>    return x * y
+    >>>    '''
+    >>>
+    >>> multiply_schema = get_json_schema(multiply)
+    >>> tokenizer = AutoTokenizer.from_pretrained("CohereForAI/c4ai-command-r-v01")
+    >>> messages = [{"role": "user", "content": "What is 179 x 4571?"}]
+    >>> formatted_chat = tokenizer.apply_chat_template(
+    >>>     messages,
+    >>>     tools=[multiply_schema],
+    >>>     chat_template="tool_use",
+    >>>     return_dict=True,
+    >>>     return_tensors="pt",
+    >>>     add_generation_prompt=True
+    >>> )
+    >>> # The formatted chat can now be passed to model.generate()
+    ```
+
+    Each argument description can also have an optional `(choices: ...)` block at the end, such as
+    `(choices: ["tea", "coffee"])`, which will be parsed into an `enum` field in the schema. Note that this will
+    only be parsed correctly if it is at the end of the line:
+
+    ```python
+    >>> def drink_beverage(beverage: str):
+    >>>    '''
+    >>>    A function that drinks a beverage
+    >>>
+    >>>    Args:

+    Function or method decorator to notify users about deprecated keyword arguments, replacing them with a new name if specified.
+    Note that is decorator is `torch.compile`-safe, i.e. it will not cause graph breaks (but no warning will be displayed if compiling).
+
+    This decorator allows you to:
+    - Notify users when a keyword argument is deprecated.
+    - Automatically replace deprecated keyword arguments with new ones.
+    - Raise an error if deprecated arguments are used, depending on the specified conditions.
+
+    By default, the decorator notifies the user about the deprecated argument while the `transformers.__version__` < specified `version`
+    in the decorator. To keep notifications with any version `warn_if_greater_or_equal_version=True` can be set.
+
+    Parameters:
+        old_name (`str`):
+            Name of the deprecated keyword argument.
+        version (`str`):
+            The version in which the keyword argument was (or will be) deprecated.
+        new_name (`Optional[str]`, *optional*):
+            The new name for the deprecated keyword argument. If specified, the deprecated keyword argument will be replaced with this new name.
+        warn_if_greater_or_equal_version (`bool`, *optional*, defaults to `False`):
+            Whether to show warning if current `transformers` version is greater or equal to the deprecated version.
+        raise_if_greater_or_equal_version (`bool`, *optional*, defaults to `False`):
+            Whether to raise `ValueError` if current `transformers` version is greater or equal to the deprecated version.
+        raise_if_both_names (`bool`, *optional*, defaults to `False`):
+            Whether to raise `ValueError` if both deprecated and new keyword arguments are set.
+        additional_message (`Optional[str]`, *optional*):
+            An additional message to append to the default deprecation message.
+
+    Raises:
+        ValueError:
+            If raise_if_greater_or_equal_version is True and the current version is greater than or equal to the deprecated version, or if raise_if_both_names is True and both old and new keyword arguments are provided.
+
+    Returns:
+        Callable:
+            A wrapped function that handles the deprecated keyword arguments according to the specified parameters.
+
+    Example usage with renaming argument:
+
+        ```python
+        @deprecate_kwarg("reduce_labels", new_name="do_reduce_labels", version="6.0.0")
+        def my_function(do_reduce_labels):

+
+        my_function(reduce_labels=True)  # Will show a deprecation warning and use do_reduce_labels=True

+                Whether or not to create a PR with the uploaded files or directly commit.
+            safe_serialization (`bool`, *optional*, defaults to `True`):
+                Whether or not to convert the model weights in safetensors format for safer serialization.

+    This method takes the path to a file/a folder and returns the import structure.
+    If a file is given, it will return the import structure of the parent folder.
+
+    Import structures are designed to be digestible by `_LazyModule` objects. They are
+    created from the __all__ definitions in each files as well as the `@export` decorators
+    above methods and objects.
+
+    The import structure allows explicit display of the required backends for a given object.
+    These backends are specified in two ways:
+
+    1. Through their `@export`, if they are exported with that decorator. This `@export` decorator
+       accepts a `backend` tuple kwarg mentioning which backends are required to run this object.
+
+    2. If an object is defined in a file with "default" backends, it will have, at a minimum, this
+       backend specified. The default backends are defined according to the filename:
+
+       - If a file is named like `modeling_*.py`, it will have a `torch` backend
+       - If a file is named like `modeling_tf_*.py`, it will have a `tf` backend
+       - If a file is named like `modeling_flax_*.py`, it will have a `flax` backend
+       - If a file is named like `tokenization_*_fast.py`, it will have a `tokenizers` backend
+
+    Backends serve the purpose of displaying a clear error message to the user in case the backends are not installed.
+    Should an object be imported without its required backends being in the environment, any attempt to use the
+    object will raise an error mentioning which backend(s) should be added to the environment in order to use
+    that object.

+    Currently only supports `LLM.int8()`, `FP4`, and `NF4` quantization. If more methods are added to `bitsandbytes`,
+    then more arguments will be added to this class.
+
+    Args:
+        load_in_8bit (`bool`, *optional*, defaults to `False`):
+            This flag is used to enable 8-bit quantization with LLM.int8().
+        load_in_4bit (`bool`, *optional*, defaults to `False`):
+            This flag is used to enable 4-bit quantization by replacing the Linear layers with FP4/NF4 layers from
+            `bitsandbytes`.
+        llm_int8_threshold (`float`, *optional*, defaults to 6.0):
+            This corresponds to the outlier threshold for outlier detection as described in `LLM.int8() : 8-bit Matrix
+            Multiplication for Transformers at Scale` paper: https://arxiv.org/abs/2208.07339 Any hidden states value
+            that is above this threshold will be considered an outlier and the operation on those values will be done
+            in fp16. Values are usually normally distributed, that is, most values are in the range [-3.5, 3.5], but
+            there are some exceptional systematic outliers that are very differently distributed for large models.
+            These outliers are often in the interval [-60, -6] or [6, 60]. Int8 quantization works well for values of
+            magnitude ~5, but beyond that, there is a significant performance penalty. A good default threshold is 6,
+            but a lower threshold might be needed for more unstable models (small models, fine-tuning).
+        llm_int8_skip_modules (`List[str]`, *optional*):
+            An explicit list of the modules that we do not want to convert in 8-bit. This is useful for models such as
+            Jukebox that has several heads in different places and not necessarily at the last position. For example
+            for `CausalLM` models, the last `lm_head` is kept in its original `dtype`.
+        llm_int8_enable_fp32_cpu_offload (`bool`, *optional*, defaults to `False`):
+            This flag is used for advanced use cases and users that are aware of this feature. If you want to split
+            your model in different parts and run some parts in int8 on GPU and some parts in fp32 on CPU, you can use
+            this flag. This is useful for offloading large models such as `google/flan-t5-xxl`. Note that the int8
+            operations will not be run on CPU.
+        llm_int8_has_fp16_weight (`bool`, *optional*, defaults to `False`):
+            This flag runs LLM.int8() with 16-bit main weights. This is useful for fine-tuning as the weights do not
+            have to be converted back and forth for the backward pass.
+        bnb_4bit_compute_dtype (`torch.dtype` or str, *optional*, defaults to `torch.float32`):
+            This sets the computational type which might be different than the input type. For example, inputs might be
+            fp32, but computation can be set to bf16 for speedups.
+        bnb_4bit_quant_type (`str`,  *optional*, defaults to `"fp4"`):
+            This sets the quantization data type in the bnb.nn.Linear4Bit layers. Options are FP4 and NF4 data types
+            which are specified by `fp4` or `nf4`.
+        bnb_4bit_use_double_quant (`bool`, *optional*, defaults to `False`):
+            This flag is used for nested quantization where the quantization constants from the first quantization are
+            quantized again.
+        bnb_4bit_quant_storage (`torch.dtype` or str, *optional*, defaults to `torch.uint8`):
+            This sets the storage type to pack the quanitzed 4-bit prarams.
+        kwargs (`Dict[str, Any]`, *optional*):
+            Additional parameters from which to initialize the configuration object.

+        tokenizer (`str` or `PreTrainedTokenizerBase`, *optional*):
+            The tokenizer used to process the dataset. You can pass either:
+                - A custom tokenizer object.
+                - A string, the *model id* of a predefined tokenizer hosted inside a model repo on huggingface.co.

+            original datasets used in GPTQ paper ['wikitext2','c4','c4-new']
+        group_size (`int`, *optional*, defaults to 128):
+            The group size to use for quantization. Recommended value is 128 and -1 uses per-column quantization.
+        damp_percent (`float`, *optional*, defaults to 0.1):
+            The percent of the average Hessian diagonal to use for dampening. Recommended value is 0.1.
+        desc_act (`bool`, *optional*, defaults to `False`):
+            Whether to quantize columns in order of decreasing activation size. Setting it to False can significantly
+            speed up inference but the perplexity may become slightly worse. Also known as act-order.

+            Whether to use symetric quantization.
+        true_sequential (`bool`, *optional*, defaults to `True`):
+            Whether to perform sequential quantization even within a single Transformer block. Instead of quantizing
+            the entire block at once, we perform layer-wise quantization. As a result, each layer undergoes

+        checkpoint_format (`str`, *optional*, defaults to `"gptq"`):
+            GPTQ weight format. `gptq`(v1) is supported by both gptqmodel and auto-gptq. `gptq_v2` is gptqmodel only.
+        meta (`Dict[str, any]`, *optional*):
+            Properties, such as tooling:version, that do not directly contributes to quantization or quant inference are stored in meta.
+            i.e. `meta.quantizer`: ["optimum:_version_", "gptqmodel:_version_"]
+        backend (`str`, *optional*):
+            Controls which gptq kernel to be used. Valid values for gptqmodel are `auto`, `auto_trainable` and more. For auto-gptq, only
+            valid value is None and `auto_trainable`. Ref gptqmodel backends: https://github.com/ModelCloud/GPTQModel/blob/main/gptqmodel/utils/backend.py
+        use_cuda_fp16 (`bool`, *optional*, defaults to `False`):
+            Whether or not to use optimized cuda kernel for fp16 model. Need to have model in fp16. Auto-gptq only.
+        model_seqlen (`int`, *optional*):
+            The maximum sequence length that the model can take.
+        block_name_to_quantize (`str`, *optional*):
+            The transformers block name to quantize. If None, we will infer the block name using common patterns (e.g. model.layers)
+        module_name_preceding_first_block (`List[str]`, *optional*):
+            The layers that are preceding the first Transformer block.
+        batch_size (`int`, *optional*, defaults to 1):
+            The batch size used when processing the dataset
+        pad_token_id (`int`, *optional*):
+            The pad token id. Needed to prepare the dataset when `batch_size` > 1.
+        use_exllama (`bool`, *optional*):
+            Whether to use exllama backend. Defaults to `True` if unset. Only works with `bits` = 4.
+        max_input_length (`int`, *optional*):
+            The maximum input length. This is needed to initialize a buffer that depends on the maximum expected input
+            length. It is specific to the exllama backend with act-order.
+        exllama_config (`Dict[str, Any]`, *optional*):
+            The exllama config. You can specify the version of the exllama kernel through the `version` key. Defaults
+            to `{"version": 1}` if unset.
+        cache_block_outputs (`bool`, *optional*, defaults to `True`):
+            Whether to cache block outputs to reuse as inputs for the succeeding block.
+        modules_in_block_to_quantize (`List[List[str]]`, *optional*):
+            List of list of module names to quantize in the specified block. This argument is useful to exclude certain linear modules from being quantized.
+            The block to quantize can be specified by setting `block_name_to_quantize`. We will quantize each list sequentially. If not set, we will quantize all linear layers.
+            Example: `modules_in_block_to_quantize =[["self_attn.k_proj", "self_attn.v_proj", "self_attn.q_proj"], ["self_attn.o_proj"]]`.
+            In this example, we will first quantize the q,k,v layers simultaneously since they are independent.
+            Then, we will quantize `self_attn.o_proj` layer with the q,k,v layers quantized. This way, we will get
+            better results since it reflects the real input `self_attn.o_proj` will get when the model is quantized.

+
+This folder contains a template to add a tokenization test. 
+
+## Usage
+
+Using the `cookiecutter` utility requires to have all the `dev` dependencies installed. 
+
+Let's first [fork](https://docs.github.com/en/get-started/quickstart/fork-a-repo) the `transformers` repo on github. Once it's done you can clone your fork and install `transformers` in our environment:
+
+```shell script
+git clone https://github.com/YOUR-USERNAME/transformers
+cd transformers
+pip install -e ".[dev]"
+```
+
+Once the installation is done, you can generate the template by running the following command. Be careful, the template will be generated inside a new folder in your current working directory.
+
+```shell script
+cookiecutter path-to-the folder/adding_a_missing_tokenization_test/
+```
+
+You will then have to answer some questions about the tokenizer for which you want to add tests. The `modelname` should be cased according to the plain text casing, i.e., BERT, RoBERTa, DeBERTa.
+
+Once the command has finished, you should have a one new file inside the newly created folder named `test_tokenization_Xxx.py`. At this point the template is finished and you can move it to the sub-folder of the corresponding model in the test folder.

+# How to add a new example script in 🤗 Transformers
+
+This folder provide a template for adding a new example script implementing a training or inference task with the
+models in the 🤗 Transformers library. To use it, you will need to install cookiecutter:
+```bash
+pip install cookiecutter
+```
+or refer to the installation page of the [cookiecutter documentation](https://cookiecutter.readthedocs.io/).
+
+You can then run the following command inside the `examples` folder of the transformers repo:
+```bash
+cookiecutter ../templates/adding_a_new_example_script/
+```
+and answer the questions asked, which will generate a new folder where you will find a pre-filled template for your
+example following the best practices we recommend for them.
+
+Adjust the way the data is preprocessed, the model is loaded or the Trainer is instantiated then when you're happy, add
+a `README.md` in the folder (or complete the existing one if you added a script to an existing folder) telling a user
+how to run your script.
+
+Make a PR to the 🤗 Transformers repo. Don't forget to tweet about your new example with a carbon screenshot of how to
+run it and tag @huggingface!

+How to add [camelcase name of model] to 🤗 Transformers?
+=====================================

+Mentor: [name of mentor]

+Begin: [start date]

+Estimated End: [end date]
+
+Adding a new model is often difficult and requires an in-depth knowledge
+of the 🤗 Transformers library and ideally also of the model's original
+repository. At Hugging Face, we are trying to empower the community more
+and more to add models independently. 
+
+The following sections explain in detail how to add [camelcase name of model] 
+to Transformers. You will work closely with [name of mentor] to
+integrate [camelcase name of model] into Transformers. By doing so, you will both gain a 
+theoretical and deep practical understanding of [camelcase name of model]. 
+But more importantly, you will have made a major
+open-source contribution to Transformers. Along the way, you will:
+
+-   get insights into open-source best practices
+-   understand the design principles of one of the most popular NLP
+    libraries
+-   learn how to do efficiently test large NLP models
+-   learn how to integrate Python utilities like `black`, `ruff`,
+    `make fix-copies` into a library to always ensure clean and readable
+    code
+
+To start, let's try to get a general overview of the Transformers
+library.
+
+General overview of 🤗 Transformers
+----------------------------------
+
+First, you should get a general overview of 🤗 Transformers. Transformers 
+is a very opinionated library, so there is a chance that
+you don't agree with some of the library's philosophies or design
+choices. From our experience, however, we found that the fundamental
+design choices and philosophies of the library are crucial to
+efficiently scale Transformers while keeping maintenance costs at a
+reasonable level.
+
+A good first starting point to better understand the library is to read
+the [documentation of our philosophy](https://huggingface.co/transformers/philosophy.html).
+As a result of our way of working, there are some choices that we try to apply to all models:
+
+-   Composition is generally favored over abstraction
+-   Duplicating code is not always bad if it strongly improves the
+    readability or accessibility of a model
+-   Model files are as self-contained as possible so that when you read
+    the code of a specific model, you ideally only have to look into the
+    respective `modeling_....py` file.
+
+In our opinion, the library's code is not just a means to provide a
+product, *e.g.*, the ability to use BERT for inference, but also as the
+very product that we want to improve. Hence, when adding a model, the
+user is not only the person that will use your model, but also everybody
+that will read, try to understand, and possibly tweak your code.
+
+With this in mind, let's go a bit deeper into the general library
+design.
+
+### Overview of models
+
+To successfully add a model, it is important to understand the
+interaction between your model and its config,
+`PreTrainedModel`, and `PretrainedConfig`. For
+exemplary purposes, we will call the PyTorch model to be added to 🤗 Transformers
+`BrandNewBert`.
+
+Let's take a look:
+
+![image](https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers_overview.png)
+
+As you can see, we do make use of inheritance in 🤗 Transformers, but we
+keep the level of abstraction to an absolute minimum. There are never
+more than two levels of abstraction for any model in the library.
+`BrandNewBertModel` inherits from
+`BrandNewBertPreTrainedModel` which in
+turn inherits from `PreTrainedModel` and that's it. 
+As a general rule, we want to make sure
+that a new model only depends on `PreTrainedModel`. The
+important functionalities that are automatically provided to every new
+model are
+`PreTrainedModel.from_pretrained` and `PreTrainedModel.save_pretrained`, which are 
+used for serialization and deserialization. All
+of the other important functionalities, such as
+`BrandNewBertModel.forward` should be
+completely defined in the new `modeling_brand_new_bert.py` module. Next,
+we want to make sure that a model with a specific head layer, such as
+`BrandNewBertForMaskedLM` does not inherit
+from `BrandNewBertModel`, but rather uses
+`BrandNewBertModel` as a component that
+can be called in its forward pass to keep the level of abstraction low.
+Every new model requires a configuration class, called
+`BrandNewBertConfig`. This configuration
+is always stored as an attribute in
+`PreTrainedModel`, and
+thus can be accessed via the `config` attribute for all classes
+inheriting from `BrandNewBertPreTrainedModel`
+
+```python
+# assuming that `brand_new_bert` belongs to the organization `brandy`
+model = BrandNewBertModel.from_pretrained("brandy/brand_new_bert")
+model.config  # model has access to its config
+```
+
+Similar to the model, the configuration inherits basic serialization and
+deserialization functionalities from
+`PretrainedConfig`. Note
+that the configuration and the model are always serialized into two
+different formats - the model to a `pytorch_model.bin` file
+and the configuration to a `config.json` file. Calling
+`PreTrainedModel.save_pretrained` will automatically call
+`PretrainedConfig.save_pretrained`, so that both model and configuration are saved.
+
+### Overview of tokenizers
+
+Not quite ready yet :-( This section will be added soon!
+
+Step-by-step recipe to add a model to 🤗 Transformers
+----------------------------------------------------
+
+Everyone has different preferences of how to port a model so it can be
+very helpful for you to take a look at summaries of how other
+contributors ported models to Hugging Face. Here is a list of community
+blog posts on how to port a model:
+
+1.  [Porting GPT2
+    Model](https://medium.com/huggingface/from-tensorflow-to-pytorch-265f40ef2a28)
+    by [Thomas](https://huggingface.co/thomwolf)
+2.  [Porting WMT19 MT Model](https://huggingface.co/blog/porting-fsmt)
+    by [Stas](https://huggingface.co/stas)
+
+From experience, we can tell you that the most important things to keep
+in mind when adding a model are:
+
+-   Don't reinvent the wheel! Most parts of the code you will add for
+    the new 🤗 Transformers model already exist somewhere in 🤗
+    Transformers. Take some time to find similar, already existing
+    models and tokenizers you can copy from.
+    [grep](https://www.gnu.org/software/grep/) and
+    [rg](https://github.com/BurntSushi/ripgrep) are your friends. Note
+    that it might very well happen that your model's tokenizer is based
+    on one model implementation, and your model's modeling code on
+    another one. *E.g.*, FSMT's modeling code is based on BART, while
+    FSMT's tokenizer code is based on XLM.
+-   It's more of an engineering challenge than a scientific challenge.
+    You should spend more time on creating an efficient debugging
+    environment than trying to understand all theoretical aspects of the
+    model in the paper.
+-   Ask for help when you're stuck! Models are the core component of 🤗
+    Transformers so we, at Hugging Face, are more than happy to help
+    you at every step to add your model. Don't hesitate to ask if you
+    notice you are not making progress.
+
+In the following, we try to give you a general recipe that we found most
+useful when porting a model to 🤗 Transformers.
+
+The following list is a summary of everything that has to be done to add
+a model and can be used by you as a To-Do List:

+12. [ ] Uploaded model weights to the hub
+
+13. [ ] Submitted the pull request for review
+
+14. [ ] (Optional) Added a demo notebook
+
+To begin with, we usually recommend to start by getting a good
+theoretical understanding of `[camelcase name of model]`. However, if you prefer to
+understand the theoretical aspects of the model *on-the-job*, then it is
+totally fine to directly dive into the `[camelcase name of model]`'s code-base. This
+option might suit you better, if your engineering skills are better than
+your theoretical skill, if you have trouble understanding
+`[camelcase name of model]`'s paper, or if you just enjoy programming much more than
+reading scientific papers.
+
+### 1. (Optional) Theoretical aspects of [camelcase name of model]
+
+You should take some time to read *[camelcase name of model]'s* paper, if such
+descriptive work exists. There might be large sections of the paper that
+are difficult to understand. If this is the case, this is fine - don't
+worry! The goal is not to get a deep theoretical understanding of the
+paper, but to extract the necessary information required to effectively
+re-implement the model in 🤗 Transformers. That being said, you don't
+have to spend too much time on the theoretical aspects, but rather focus
+on the practical ones, namely:
+
+-   What type of model is *[camelcase name of model]*? BERT-like encoder-only
+    model? GPT2-like decoder-only model? BART-like encoder-decoder
+    model? Look at the `model_summary` if
+    you're not familiar with the differences between those.
+-   What are the applications of *[camelcase name of model]*? Text
+    classification? Text generation? Seq2Seq tasks, *e.g.,*
+    summarization?
+-   What is the novel feature of the model making it different from
+    BERT/GPT-2/BART?
+-   Which of the already existing [🤗 Transformers
+    models](https://huggingface.co/transformers/#contents) is most
+    similar to *[camelcase name of model]*?
+-   What type of tokenizer is used? A sentencepiece tokenizer? Word
+    piece tokenizer? Is it the same tokenizer as used for BERT or BART?
+
+After you feel like you have gotten a good overview of the architecture
+of the model, you might want to write to [name of mentor] with any
+questions you might have. This might include questions regarding the
+model's architecture, its attention layer, etc. We will be more than
+happy to help you.
+
+
+#### Additional resources
+
+ Before diving into the code, here are some additional resources that might be worth taking a look at:
+ 
+ - [link 1]
+ - [link 2]
+ - [link 3]
+ - ...
+
+#### Make sure you've understood the fundamental aspects of [camelcase name of model]
+
+Alright, now you should be ready to take a closer look into the actual code of [camelcase name of model].
+You should have understood the following aspects of [camelcase name of model] by now:
+
+- [characteristic 1 of [camelcase name of model]]
+- [characteristic 2 of [camelcase name of model]]
+- ...
+
+If any of the mentioned aspects above are **not** clear to you, now is a great time to talk to [name of mentor].
+
+### 2. Next prepare your environment
+
+1.  Fork the [repository](https://github.com/huggingface/transformers)
+    by clicking on the 'Fork' button on the repository's page. This
+    creates a copy of the code under your GitHub user account.
+
+2.  Clone your `transformers` fork to your local disk, and add the base
+    repository as a remote:
+
+    ```bash
+    git clone https://github.com/[your Github handle]/transformers.git
+    cd transformers
+    git remote add upstream https://github.com/huggingface/transformers.git
+    ```
+
+3.  Set up a development environment, for instance by running the
+    following command:
+
+    ```bash
+    python -m venv .env
+    source .env/bin/activate
+    pip install -e ".[dev]"
+    ```
+
+and return to the parent directory
+
+```bash
+cd ..
+```
+
+4.  We recommend adding the PyTorch version of *[camelcase name of model]* to
+    Transformers. To install PyTorch, please follow the instructions [here](https://pytorch.org/get-started/locally/).
+
+**Note:** You don't need to have CUDA installed. Making the new model
+work on CPU is sufficient.
+
+5.  To port *[camelcase name of model]*, you will also need access to its
+    original repository:
+
+```bash
+git clone [link to original repo].git 
+cd [lowercase name of model]
+pip install -e .
+```
+
+Now you have set up a development environment to port *[camelcase name of model]*
+to 🤗 Transformers.
+
+### Run a pretrained checkpoint using the original repository
+
+**3. Set up debugging environment**
+
+At first, you will work on the original *[camelcase name of model]* repository.
+Often, the original implementation is very "researchy". Meaning that
+documentation might be lacking and the code can be difficult to
+understand. But this should be exactly your motivation to reimplement
+*[camelcase name of model]*. At Hugging Face, one of our main goals is to *make
+people stand on the shoulders of giants* which translates here very well
+into taking a working model and rewriting it to make it as **accessible,
+user-friendly, and beautiful** as possible. This is the number-one
+motivation to re-implement models into 🤗 Transformers - trying to make
+complex new NLP technology accessible to **everybody**.
+
+You should start thereby by diving into the [original repository]([link to original repo]).
+
+Successfully running the official pretrained model in the original
+repository is often **the most difficult** step. From our experience, it
+is very important to spend some time getting familiar with the original
+code-base. You need to figure out the following:
+
+-   Where to find the pretrained weights?
+-   How to load the pretrained weights into the corresponding model?
+-   How to run the tokenizer independently from the model?
+-   Trace one forward pass so that you know which classes and functions
+    are required for a simple forward pass. Usually, you only have to
+    reimplement those functions.
+-   Be able to locate the important components of the model: Where is
+    the model's class? Are there model sub-classes, *e.g.*,
+    EncoderModel, DecoderModel? Where is the self-attention layer? Are
+    there multiple different attention layers, *e.g.*, *self-attention*,
+    *cross-attention*...?
+-   How can you debug the model in the original environment of the repo?
+    Do you have to add `print` statements, can you work with
+    an interactive debugger like [ipdb](https://pypi.org/project/ipdb/), or should you use
+    an efficient IDE to debug the model, like PyCharm?
+
+It is very important that before you start the porting process, that you
+can **efficiently** debug code in the original repository! Also,
+remember that you are working with an open-source library, so do not
+hesitate to open an issue, or even a pull request in the original
+repository. The maintainers of this repository are most likely very
+happy about someone looking into their code!
+
+At this point, it is really up to you which debugging environment and
+strategy you prefer to use to debug the original model. We strongly
+advise against setting up a costly GPU environment, but simply work on a
+CPU both when starting to dive into the original repository and also
+when starting to write the 🤗 Transformers implementation of the model.
+Only at the very end, when the model has already been successfully
+ported to 🤗 Transformers, one should verify that the model also works as
+expected on GPU.
+
+In general, there are two possible debugging environments for running
+the original model
+
+-   [Jupyter notebooks](https://jupyter.org/) / [google colab](https://colab.research.google.com/notebooks/intro.ipynb)
+-   Local python scripts.
+
+Jupyter notebooks have the advantage that they allow for cell-by-cell
+execution which can be helpful to better split logical components from
+one another and to have faster debugging cycles as intermediate results
+can be stored. Also, notebooks are often easier to share with other
+contributors, which might be very helpful if you want to ask the Hugging
+Face team for help. If you are familiar with Jupyter notebooks, we
+strongly recommend you to work with them.
+
+The obvious disadvantage of Jupyter notebooks is that if you are not
+used to working with them you will have to spend some time adjusting to
+the new programming environment and that you might not be able to use
+your known debugging tools anymore, like `ipdb`.
+
+**4. Successfully run forward pass**
+
+For each code-base, a good first step is always to load a **small**
+pretrained checkpoint and to be able to reproduce a single forward pass
+using a dummy integer vector of input IDs as an input. Such a script
+could look like this (in pseudocode):
+
+```python
+model = [camelcase name of model]Model.load_pretrained_checkpoint("/path/to/checkpoint/")
+input_ids = [0, 4, 5, 2, 3, 7, 9]  # vector of input ids
+original_output = model.predict(input_ids)
+```
+
+Next, regarding the debugging strategy, there are generally a few from
+which to choose from:
+
+-   Decompose the original model into many small testable components and
+    run a forward pass on each of those for verification
+-   Decompose the original model only into the original *tokenizer* and
+    the original *model*, run a forward pass on those, and use
+    intermediate print statements or breakpoints for verification
+
+Again, it is up to you which strategy to choose. Often, one or the other
+is advantageous depending on the original code base.
+
+If the original code-base allows you to decompose the model into smaller
+sub-components, *e.g.*, if the original code-base can easily be run in
+eager mode, it is usually worth the effort to do so. There are some
+important advantages to taking the more difficult road in the beginning:
+
+-   at a later stage when comparing the original model to the Hugging
+    Face implementation, you can verify automatically for each component
+    individually that the corresponding component of the 🤗 Transformers
+    implementation matches instead of relying on visual comparison via
+    print statements
+-   it can give you some rope to decompose the big problem of porting a
+    model into smaller problems of just porting individual components
+    and thus structure your work better
+-   separating the model into logical meaningful components will help
+    you to get a better overview of the model's design and thus to
+    better understand the model
+-   at a later stage those component-by-component tests help you to
+    ensure that no regression occurs as you continue changing your code
+
+[Lysandre's](https://gist.github.com/LysandreJik/db4c948f6b4483960de5cbac598ad4ed)
+integration checks for ELECTRA gives a nice example of how this can be
+done.
+
+However, if the original code-base is very complex or only allows
+intermediate components to be run in a compiled mode, it might be too
+time-consuming or even impossible to separate the model into smaller
+testable sub-components. A good example is [T5's
+MeshTensorFlow](https://github.com/tensorflow/mesh/tree/master/mesh_tensorflow)
+library which is very complex and does not offer a simple way to
+decompose the model into its sub-components. For such libraries, one
+often relies on verifying print statements.
+
+No matter which strategy you choose, the recommended procedure is often
+the same in that you should start to debug the starting layers first and
+the ending layers last.
+
+It is recommended that you retrieve the output, either by print
+statements or sub-component functions, of the following layers in the
+following order:
+
+1.  Retrieve the input IDs passed to the model
+2.  Retrieve the word embeddings
+3.  Retrieve the input of the first Transformer layer
+4.  Retrieve the output of the first Transformer layer
+5.  Retrieve the output of the following n - 1 Transformer layers
+6.  Retrieve the output of the whole [camelcase name of model] Model
+
+Input IDs should thereby consists of an array of integers, *e.g.*,
+`input_ids = [0, 4, 4, 3, 2, 4, 1, 7, 19]`
+
+The outputs of the following layers often consist of multi-dimensional
+float arrays and can look like this:
+
+```bash
+[[
+ [-0.1465, -0.6501,  0.1993,  ...,  0.1451,  0.3430,  0.6024],
+ [-0.4417, -0.5920,  0.3450,  ..., -0.3062,  0.6182,  0.7132],
+ [-0.5009, -0.7122,  0.4548,  ..., -0.3662,  0.6091,  0.7648],
+ ...,
+ [-0.5613, -0.6332,  0.4324,  ..., -0.3792,  0.7372,  0.9288],
+ [-0.5416, -0.6345,  0.4180,  ..., -0.3564,  0.6992,  0.9191],
+ [-0.5334, -0.6403,  0.4271,  ..., -0.3339,  0.6533,  0.8694]]],
+```
+
+We expect that every model added to 🤗 Transformers passes a couple of
+integration tests, meaning that the original model and the reimplemented
+version in 🤗 Transformers have to give the exact same output up to a
+precision of 0.001! Since it is normal that the exact same model written
+in different libraries can give a slightly different output depending on
+the library framework, we accept an error tolerance of 1e-3 (0.001). It
+is not enough if the model gives nearly the same output, they have to be
+the almost identical. Therefore, you will certainly compare the
+intermediate outputs of the 🤗 Transformers version multiple times
+against the intermediate outputs of the original implementation of
+*[camelcase name of model]* in which case an **efficient** debugging environment
+of the original repository is absolutely important. Here is some advice
+to make your debugging environment as efficient as possible.
+
+-   Find the best way of debugging intermediate results. Is the original
+    repository written in PyTorch? Then you should probably take the
+    time to write a longer script that decomposes the original model
+    into smaller sub-components to retrieve intermediate values. Is the
+    original repository written in Tensorflow 1? Then you might have to
+    rely on TensorFlow print operations like
+    [tf.print](https://www.tensorflow.org/api_docs/python/tf/print) to
+    output intermediate values. Is the original repository written in
+    Jax? Then make sure that the model is **not jitted** when running
+    the forward pass, *e.g.*, check-out [this
+    link](https://github.com/google/jax/issues/196).
+-   Use the smallest pretrained checkpoint you can find. The smaller the
+    checkpoint, the faster your debug cycle becomes. It is not efficient
+    if your pretrained model is so big that your forward pass takes more
+    than 10 seconds. In case only very large checkpoints are available,
+    it might make more sense to create a dummy model in the new
+    environment with randomly initialized weights and save those weights
+    for comparison with the 🤗 Transformers version of your model
+-   Make sure you are using the easiest way of calling a forward pass in
+    the original repository. Ideally, you want to find the function in
+    the original repository that **only** calls a single forward pass,
+    *i.e.* that is often called `predict`, `evaluate`, `forward` or
+    `__call__`. You don't want to debug a function that calls `forward`
+    multiple times, *e.g.*, to generate text, like
+    `autoregressive_sample`, `generate`.
+-   Try to separate the tokenization from the model's
+    forward pass. If the original repository shows
+    examples where you have to input a string, then try to find out
+    where in the forward call the string input is changed to input ids
+    and start from this point. This might mean that you have to possibly
+    write a small script yourself or change the original code so that
+    you can directly input the ids instead of an input string.
+-   Make sure that the model in your debugging setup is **not** in
+    training mode, which often causes the model to yield random outputs
+    due to multiple dropout layers in the model. Make sure that the
+    forward pass in your debugging environment is **deterministic** so
+    that the dropout layers are not used. Or use
+    `transformers.utils.set_seed` if the old and new
+    implementations are in the same framework.
+
+#### More details on how to create a debugging environment for [camelcase name of model] 
+
+[TODO FILL: Here the mentor should add very specific information on what the student should do]
+[to set up an efficient environment for the special requirements of this model]
+
+### Port [camelcase name of model] to 🤗 Transformers
+
+Next, you can finally start adding new code to 🤗 Transformers. Go into
+the clone of your 🤗 Transformers' fork:
+
+    cd transformers
+
+In the special case that you are adding a model whose architecture
+exactly matches the model architecture of an existing model you only
+have to add a conversion script as described in [this
+section](#write-a-conversion-script). In this case, you can just re-use
+the whole model architecture of the already existing model.
+
+Otherwise, let's start generating a new model with the amazing
+Cookiecutter!
+
+**Use the Cookiecutter to automatically generate the model's code**
+
+To begin with head over to the [🤗 Transformers
+templates](https://github.com/huggingface/transformers/tree/main/templates/adding_a_new_model)
+to make use of our `cookiecutter` implementation to automatically
+generate all the relevant files for your model. Again, we recommend only
+adding the PyTorch version of the model at first. Make sure you follow
+the instructions of the `README.md` on the [🤗 Transformers
+templates](https://github.com/huggingface/transformers/tree/main/templates/adding_a_new_model)
+carefully.
+
+**Open a Pull Request on the main huggingface/transformers repo**
+
+Before starting to adapt the automatically generated code, now is the
+time to open a "Work in progress (WIP)" pull request, *e.g.*, "\[WIP\]
+Add *[camelcase name of model]*", in 🤗 Transformers so that you and the Hugging
+Face team can work side-by-side on integrating the model into 🤗
+Transformers.
+
+You should do the following:
+
+1.  Create a branch with a descriptive name from your main branch
+
+```bash
+    git checkout -b add_[lowercase name of model]
+```
+
+2.  Commit the automatically generated code:
+
+```bash
+    git add .
+    git commit
+```
+
+3.  Fetch and rebase to current main
+
+```bash
+    git fetch upstream
+    git rebase upstream/main
+```
+
+4.  Push the changes to your account using:
+
+```bash
+    git push -u origin a-descriptive-name-for-my-changes
+```
+
+5.  Once you are satisfied, go to the webpage of your fork on GitHub.
+    Click on "Pull request". Make sure to add the GitHub handle of 
+		[name of mentor] as a reviewer, so that the Hugging
+    Face team gets notified for future changes.
+
+6.  Change the PR into a draft by clicking on "Convert to draft" on the
+    right of the GitHub pull request web page.
+
+In the following, whenever you have done some progress, don't forget to
+commit your work and push it to your account so that it shows in the
+pull request. Additionally, you should make sure to update your work
+with the current main from time to time by doing:
+
+    git fetch upstream
+    git merge upstream/main
+
+In general, all questions you might have regarding the model or your
+implementation should be asked in your PR and discussed/solved in the
+PR. This way, [name of mentor] will always be notified when you are
+committing new code or if you have a question. It is often very helpful
+to point [name of mentor] to your added code so that the Hugging
+Face team can efficiently understand your problem or question.
+
+To do so, you can go to the "Files changed" tab where you see all of
+your changes, go to a line regarding which you want to ask a question,
+and click on the "+" symbol to add a comment. Whenever a question or
+problem has been solved, you can click on the "Resolve" button of the
+created comment.
+
+In the same way, [name of mentor] will open comments when reviewing
+your code. We recommend asking most questions on GitHub on your PR. For
+some very general questions that are not very useful for the public,
+feel free to ping [name of mentor] by Slack or email.
+
+**5. Adapt the generated models code for [camelcase name of model]**
+
+At first, we will focus only on the model itself and not care about the
+tokenizer. All the relevant code should be found in the generated files
+`src/transformers/models/[lowercase name of model]/modeling_[lowercase name of model].py` and
+`src/transformers/models/[lowercase name of model]/configuration_[lowercase name of model].py`.
+
+Now you can finally start coding :). The generated code in
+`src/transformers/models/[lowercase name of model]/modeling_[lowercase name of model].py` will
+either have the same architecture as BERT if it's an encoder-only model
+or BART if it's an encoder-decoder model. At this point, you should
+remind yourself what you've learned in the beginning about the
+theoretical aspects of the model: *How is the model different from BERT
+or BART?*\". Implement those changes which often means to change the
+*self-attention* layer, the order of the normalization layer, etc...
+Again, it is often useful to look at the similar architecture of already
+existing models in Transformers to get a better feeling of how your
+model should be implemented.
+
+**Note** that at this point, you don't have to be very sure that your
+code is fully correct or clean. Rather, it is advised to add a first
+*unclean*, copy-pasted version of the original code to
+`src/transformers/models/[lowercase name of model]/modeling_[lowercase name of model].py`
+until you feel like all the necessary code is added. From our
+experience, it is much more efficient to quickly add a first version of
+the required code and improve/correct the code iteratively with the
+conversion script as described in the next section. The only thing that
+has to work at this point is that you can instantiate the 🤗 Transformers
+implementation of *[camelcase name of model]*, *i.e.* the following command
+should work:
+
+```python
+from transformers import [camelcase name of model]Model, [camelcase name of model]Config
+model = [camelcase name of model]Model([camelcase name of model]Config())
+```
+
+The above command will create a model according to the default
+parameters as defined in `[camelcase name of model]Config()` with random weights,
+thus making sure that the `init()` methods of all components works.
+
+[TODO FILL: Here the mentor should add very specific information on what exactly has to be changed for this model]
+[...]
+[...]
+
+**6. Write a conversion script**
+
+Next, you should write a conversion script that lets you convert the
+checkpoint you used to debug *[camelcase name of model]* in the original
+repository to a checkpoint compatible with your just created 🤗
+Transformers implementation of *[camelcase name of model]*. It is not advised to
+write the conversion script from scratch, but rather to look through
+already existing conversion scripts in 🤗 Transformers for one that has
+been used to convert a similar model that was written in the same
+framework as *[camelcase name of model]*. Usually, it is enough to copy an
+already existing conversion script and slightly adapt it for your use
+case. Don't hesitate to ask [name of mentor] to point you to a
+similar already existing conversion script for your model.
+
+-   If you are porting a model from TensorFlow to PyTorch, a good
+    starting point might be BERT's conversion script
+    [here](https://github.com/huggingface/transformers/blob/7acfa95afb8194f8f9c1f4d2c6028224dbed35a2/src/transformers/models/bert/modeling_bert.py#L91)
+-   If you are porting a model from PyTorch to PyTorch, a good starting
+    point might be BART's conversion script
+    [here](https://github.com/huggingface/transformers/blob/main/src/transformers/models/bart/convert_bart_original_pytorch_checkpoint_to_pytorch.py)
+
+In the following, we'll quickly explain how PyTorch models store layer
+weights and define layer names. In PyTorch, the name of a layer is
+defined by the name of the class attribute you give the layer. Let's
+define a dummy model in PyTorch, called `SimpleModel` as follows:
+
+```python
+from torch import nn
+
+class SimpleModel(nn.Module):
+    def __init__(self):
+            super().__init__()
+            self.dense = nn.Linear(10, 10)
+            self.intermediate = nn.Linear(10, 10)
+            self.layer_norm = nn.LayerNorm(10)
+```
+
+Now we can create an instance of this model definition which will fill
+all weights: `dense`, `intermediate`, `layer_norm` with random weights.
+We can print the model to see its architecture
+
+```python
+model = SimpleModel()
+
+print(model)
+```
+
+This will print out the following:
+
+```bash
+SimpleModel(
+  (dense): Linear(in_features=10, out_features=10, bias=True)
+  (intermediate): Linear(in_features=10, out_features=10, bias=True)
+  (layer_norm): LayerNorm((10,), eps=1e-05, elementwise_affine=True)
+)
+```
+
+We can see that the layer names are defined by the name of the class
+attribute in PyTorch. You can print out the weight values of a specific
+layer:
+
+```python
+print(model.dense.weight.data)
+```
+
+to see that the weights were randomly initialized
+
+```bash
+tensor([[-0.0818,  0.2207, -0.0749, -0.0030,  0.0045, -0.1569, -0.1598,  0.0212,
+         -0.2077,  0.2157],
+        [ 0.1044,  0.0201,  0.0990,  0.2482,  0.3116,  0.2509,  0.2866, -0.2190,
+          0.2166, -0.0212],
+        [-0.2000,  0.1107, -0.1999, -0.3119,  0.1559,  0.0993,  0.1776, -0.1950,
+         -0.1023, -0.0447],
+        [-0.0888, -0.1092,  0.2281,  0.0336,  0.1817, -0.0115,  0.2096,  0.1415,
+         -0.1876, -0.2467],
+        [ 0.2208, -0.2352, -0.1426, -0.2636, -0.2889, -0.2061, -0.2849, -0.0465,

+          0.2132,  0.1680],
+        [ 0.1733, -0.2407, -0.1721,  0.1484,  0.0358, -0.0633, -0.0721, -0.0090,
+          0.2707, -0.2509],
+        [-0.1173,  0.1561,  0.2945,  0.0595, -0.1996,  0.2988, -0.0802,  0.0407,
+          0.1829, -0.1568],
+        [-0.1164, -0.2228, -0.0403,  0.0428,  0.1339,  0.0047,  0.1967,  0.2923,
+          0.0333, -0.0536],

+          0.2220,  0.2358]]).
+```
+
+In the conversion script, you should fill those randomly initialized
+weights with the exact weights of the corresponding layer in the
+checkpoint. *E.g.*,
+
+```python
+# retrieve matching layer weights, e.g. by 
+# recursive algorithm
+layer_name = "dense"
+pretrained_weight = array_of_dense_layer
+
+model_pointer = getattr(model, "dense")
+
+model_pointer.weight.data = torch.from_numpy(pretrained_weight)
+```
+
+While doing so, you must verify that each randomly initialized weight of
+your PyTorch model and its corresponding pretrained checkpoint weight
+exactly match in both **shape and name**. To do so, it is **necessary**
+to add assert statements for the shape and print out the names of the
+checkpoints weights. *E.g.*, you should add statements like:
+
+```python
+assert (
+     model_pointer.weight.shape == pretrained_weight.shape
+), f"Pointer shape of random weight {model_pointer.shape} and array shape of checkpoint weight {pretrained_weight.shape} mismatched"
+```
+
+Besides, you should also print out the names of both weights to make
+sure they match, *e.g.*,
+
+```python
+logger.info(f"Initialize PyTorch weight {layer_name} from {pretrained_weight.name}")
+```
+
+If either the shape or the name doesn't match, you probably assigned
+the wrong checkpoint weight to a randomly initialized layer of the 🤗
+Transformers implementation.
+
+An incorrect shape is most likely due to an incorrect setting of the
+config parameters in `[camelcase name of model]Config()` that do not exactly match
+those that were used for the checkpoint you want to convert. However, it
+could also be that PyTorch's implementation of a layer requires the
+weight to be transposed beforehand.
+
+Finally, you should also check that **all** required weights are
+initialized and print out all checkpoint weights that were not used for
+initialization to make sure the model is correctly converted. It is
+completely normal, that the conversion trials fail with either a wrong
+shape statement or wrong name assignment. This is most likely because
+either you used incorrect parameters in `[camelcase name of model]Config()`, have a
+wrong architecture in the 🤗 Transformers implementation, you have a bug
+in the `init()` functions of one of the components of the 🤗 Transformers
+implementation or you need to transpose one of the checkpoint weights.
+
+This step should be iterated with the previous step until all weights of
+the checkpoint are correctly loaded in the Transformers model. Having
+correctly loaded the checkpoint into the 🤗 Transformers implementation,
+you can then save the model under a folder of your choice
+`/path/to/converted/checkpoint/folder` that should then contain both a
+`pytorch_model.bin` file and a `config.json` file:
+
+```python
+model.save_pretrained("/path/to/converted/checkpoint/folder")
+```
+
+[TODO FILL: Here the mentor should add very specific information on what exactly has to be done for the conversion of this model]
+[...]
+[...]
+
+**7. Implement the forward pass**
+
+Having managed to correctly load the pretrained weights into the 🤗
+Transformers implementation, you should now make sure that the forward
+pass is correctly implemented. In [Get familiar with the original
+repository](#34-run-a-pretrained-checkpoint-using-the-original-repository),
+you have already created a script that runs a forward pass of the model
+using the original repository. Now you should write an analogous script
+using the 🤗 Transformers implementation instead of the original one. It
+should look as follows:
+
+[TODO FILL: Here the model name might have to be adapted, *e.g.*, maybe [camelcase name of model]ForConditionalGeneration instead of [camelcase name of model]Model]
+
+```python
+model = [camelcase name of model]Model.from_pretrained("/path/to/converted/checkpoint/folder")
+input_ids = [0, 4, 4, 3, 2, 4, 1, 7, 19]
+output = model(input_ids).last_hidden_states
+```
+
+It is very likely that the 🤗 Transformers implementation and the
+original model implementation don't give the exact same output the very
+first time or that the forward pass throws an error. Don't be
+disappointed - it's expected! First, you should make sure that the
+forward pass doesn't throw any errors. It often happens that the wrong
+dimensions are used leading to a `"Dimensionality mismatch"`
+error or that the wrong data type object is used, *e.g.*, `torch.long`
+instead of `torch.float32`. Don't hesitate to ask [name of mentor]
+for help, if you don't manage to solve certain errors.
+
+The final part to make sure the 🤗 Transformers implementation works
+correctly is to ensure that the outputs are equivalent to a precision of
+`1e-3`. First, you should ensure that the output shapes are identical,
+*i.e.* `outputs.shape` should yield the same value for the script of the
+🤗 Transformers implementation and the original implementation. Next, you
+should make sure that the output values are identical as well. This one
+of the most difficult parts of adding a new model. Common mistakes why
+the outputs are not identical are:
+
+-   Some layers were not added, *i.e.* an activation layer
+    was not added, or the residual connection was forgotten
+-   The word embedding matrix was not tied
+-   The wrong positional embeddings are used because the original
+    implementation uses on offset
+-   Dropout is applied during the forward pass. To fix this make sure
+    `model.training is False` and that no dropout layer is
+    falsely activated during the forward pass, *i.e.* pass
+    `self.training` to [PyTorch's functional
+    dropout](https://pytorch.org/docs/stable/nn.functional.html?highlight=dropout#torch.nn.functional.dropout)
+
+The best way to fix the problem is usually to look at the forward pass
+of the original implementation and the 🤗 Transformers implementation
+side-by-side and check if there are any differences. Ideally, you should
+debug/print out intermediate outputs of both implementations of the
+forward pass to find the exact position in the network where the 🤗
+Transformers implementation shows a different output than the original
+implementation. First, make sure that the hard-coded `input_ids` in both
+scripts are identical. Next, verify that the outputs of the first
+transformation of the `input_ids` (usually the word embeddings) are
+identical. And then work your way up to the very last layer of the
+network. At some point, you will notice a difference between the two
+implementations, which should point you to the bug in the 🤗 Transformers
+implementation. From our experience, a simple and efficient way is to
+add many print statements in both the original implementation and 🤗
+Transformers implementation, at the same positions in the network
+respectively, and to successively remove print statements showing the
+same values for intermediate presentions.
+
+When you're confident that both implementations yield the same output,
+verifying the outputs with
+`torch.allclose(original_output, output, atol=1e-3)`, you're done with
+the most difficult part! Congratulations - the work left to be done
+should be a cakewalk 😊.
+
+**8. Adding all necessary model tests**
+
+At this point, you have successfully added a new model. However, it is
+very much possible that the model does not yet fully comply with the
+required design. To make sure, the implementation is fully compatible
+with 🤗 Transformers, all common tests should pass. The Cookiecutter
+should have automatically added a test file for your model, probably
+under the same `tests/test_modeling_[lowercase name of model].py`. Run this test
+file to verify that all common tests pass:
+
+```python
+pytest tests/test_modeling_[lowercase name of model].py
+```
+
+[TODO FILL: Here the mentor should add very specific information on what tests are likely to fail after having implemented the model
+, e.g. given the model, it might be very likely that `test_attention_output` fails]
+[...]
+[...]
+
+Having fixed all common tests, it is now crucial to ensure that all the
+nice work you have done is well tested, so that
+
+-   a)  The community can easily understand your work by looking at
+        specific tests of *[camelcase name of model]*
+
+-   b)  Future changes to your model will not break any important
+        feature of the model.
+
+At first, integration tests should be added. Those integration tests
+essentially do the same as the debugging scripts you used earlier to
+implement the model to 🤗 Transformers. A template of those model tests
+is already added by the Cookiecutter, called
+`[camelcase name of model]ModelIntegrationTests` and only has to be filled out by
+you. To ensure that those tests are passing, run
+
+```python
+RUN_SLOW=1 pytest -sv tests/test_modeling_[lowercase name of model].py::[camelcase name of model]ModelIntegrationTests
+```
+
+**Note:** In case you are using Windows, you should replace `RUN_SLOW=1` with `SET RUN_SLOW=1`
+
+Second, all features that are special to *[camelcase name of model]* should be
+tested additionally in a separate test under
+`[camelcase name of model]ModelTester`/`[camelcase name of model]ModelTest`. This part is often
+forgotten but is extremely useful in two ways:
+
+-   It helps to transfer the knowledge you have acquired during the
+    model addition to the community by showing how the special features
+    of *[camelcase name of model]* should work.
+-   Future contributors can quickly test changes to the model by running
+    those special tests.
+
+[TODO FILL: Here the mentor should add very specific information on what special features of the model should be tested additionally]
+[...]
+[...]
+
+**9. Implement the tokenizer**
+
+Next, we should add the tokenizer of *[camelcase name of model]*. Usually, the
+tokenizer is equivalent or very similar to an already existing tokenizer
+of 🤗 Transformers.
+
+[TODO FILL: Here the mentor should add a comment whether a new tokenizer is required or if this is not the case which existing tokenizer closest resembles 
+ [camelcase name of model]'s tokenizer and how the tokenizer should be implemented]
+ [...]
+ [...]
+
+It is very important to find/extract the original tokenizer file and to
+manage to load this file into the 🤗 Transformers' implementation of the
+tokenizer.
+
+For [camelcase name of model], the tokenizer files can be found here:
+- [To be filled out by mentor]
+
+and having implemented the 🤗 Transformers' version of the tokenizer can be loaded as follows:
+
+[To be filled out by mentor]
+
+To ensure that the tokenizer works correctly, it is recommended to first
+create a script in the original repository that inputs a string and
+returns the `input_ids`. It could look similar to this (in pseudo-code):
+
+```bash
+input_str = "This is a long example input string containing special characters .$?-, numbers 2872 234 12 and words."
+model = [camelcase name of model]Model.load_pretrained_checkpoint("/path/to/checkpoint/")
+input_ids = model.tokenize(input_str)
+```
+
+You might have to take a deeper look again into the original repository
+to find the correct tokenizer function or you might even have to do
+changes to your clone of the original repository to only output the
+`input_ids`. Having written a functional tokenization script that uses
+the original repository, an analogous script for 🤗 Transformers should
+be created. It should look similar to this:
+
+```python
+from transformers import [camelcase name of model]Tokenizer
+input_str = "This is a long example input string containing special characters .$?-, numbers 2872 234 12 and words."
+
+tokenizer = [camelcase name of model]Tokenizer.from_pretrained("/path/to/tokenizer/folder/")
+
+input_ids = tokenizer(input_str).input_ids
+```
+
+When both `input_ids` yield the same values, as a final step a tokenizer
+test file should also be added.
+
+[TODO FILL: Here mentor should point the student to test files of similar tokenizers]
+
+Analogous to the modeling test files of *[camelcase name of model]*, the
+tokenization test files of *[camelcase name of model]* should contain a couple of
+hard-coded integration tests.
+
+[TODO FILL: Here mentor should again point to an existing similar test of another model that the student can copy & adapt]
+
+**10. Run End-to-end integration tests**
+
+Having added the tokenizer, you should also add a couple of end-to-end
+integration tests using both the model and the tokenizer to
+`tests/test_modeling_[lowercase name of model].py` in 🤗 Transformers. Such a test
+should show on a meaningful text-to-text sample that the 🤗 Transformers
+implementation works as expected. A meaningful text-to-text sample can
+include *e.g.* a source-to-target-translation pair, an
+article-to-summary pair, a question-to-answer pair, etc... If none of
+the ported checkpoints has been fine-tuned on a downstream task it is
+enough to simply rely on the model tests. In a final step to ensure that
+the model is fully functional, it is advised that you also run all tests
+on GPU. It can happen that you forgot to add some `.to(self.device)`
+statements to internal tensors of the model, which in such a test would
+show in an error. In case you have no access to a GPU, the Hugging Face
+team can take care of running those tests for you.
+
+**11. Add Docstring**
+
+Now, all the necessary functionality for *[camelcase name of model]* is added -
+you're almost done! The only thing left to add is a nice docstring and
+a doc page. The Cookiecutter should have added a template file called
+`docs/source/model_doc/[lowercase name of model].rst` that you should fill out.
+Users of your model will usually first look at this page before using
+your model. Hence, the documentation must be understandable and concise.
+It is very useful for the community to add some *Tips* to show how the
+model should be used. Don't hesitate to ping [name of mentor]
+regarding the docstrings.
+
+Next, make sure that the docstring added to
+`src/transformers/models/[lowercase name of model]/modeling_[lowercase name of model].py` is
+correct and included all necessary inputs and outputs. It is always to
+good to remind oneself that documentation should be treated at least as
+carefully as the code in 🤗 Transformers since the documentation is
+usually the first contact point of the community with the model.
+
+**Code refactor**
+
+Great, now you have added all the necessary code for *[camelcase name of model]*.
+At this point, you should correct some potential incorrect code style by
+running:
+
+```bash
+make style
+```
+
+and verify that your coding style passes the quality check:
+
+```bash
+make quality
+```
+
+There are a couple of other very strict design tests in 🤗 Transformers
+that might still be failing, which shows up in the tests of your pull
+request. This is often because of some missing information in the
+docstring or some incorrect naming. [name of mentor] will surely
+help you if you're stuck here.
+
+Lastly, it is always a good idea to refactor one's code after having
+ensured that the code works correctly. With all tests passing, now it's
+a good time to go over the added code again and do some refactoring.
+
+You have now finished the coding part, congratulation! 🎉 You are
+Awesome! 😎
+
+**12. Upload the models to the model hub**
+
+In this final part, you should convert and upload all checkpoints to the
+model hub and add a model card for each uploaded model checkpoint. You
+should work alongside [name of mentor] here to decide on a fitting
+name for each checkpoint and to get the required access rights to be
+able to upload the model under the author's organization of
+*[camelcase name of model]*.
+
+It is worth spending some time to create fitting model cards for each
+checkpoint. The model cards should highlight the specific
+characteristics of this particular checkpoint, *e.g.*, On which dataset
+was the checkpoint pretrained/fine-tuned on? On what down-stream task
+should the model be used? And also include some code on how to correctly
+use the model.
+
+**13. (Optional) Add notebook**
+
+It is very helpful to add a notebook that showcases in-detail how
+*[camelcase name of model]* can be used for inference and/or fine-tuned on a
+downstream task. This is not mandatory to merge your PR, but very useful
+for the community.
+
+**14. Submit your finished PR**
+
+You're done programming now and can move to the last step, which is
+getting your PR merged into main. Usually, [name of mentor]
+should have helped you already at this point, but it is worth taking
+some time to give your finished PR a nice description and eventually add
+comments to your code, if you want to point out certain design choices
+to your reviewer.
+
+### Share your work!!
+
+Now, it's time to get some credit from the community for your work!
+Having completed a model addition is a major contribution to
+Transformers and the whole NLP community. Your code and the ported
+pre-trained models will certainly be used by hundreds and possibly even
+thousands of developers and researchers. You should be proud of your
+work and share your achievement with the community.
+
+**You have made another model that is super easy to access for everyone
+in the community! 🤯**

+How to add BigBird to 🤗 Transformers?
+=====================================

+Begin: 12.02.2020
+
+Estimated End: 19.03.2020
+
+Contributor: [Vasudev](https://github.com/thevasudevgupta)
+
+Adding a new model is often difficult and requires an in-depth knowledge
+of the 🤗 Transformers library and ideally also of the model's original
+repository. At Hugging Face, we are trying to empower the community more
+and more to add models independently. 
+
+The following sections explain in detail how to add BigBird 
+to Transformers. You will work closely with Patrick to
+integrate BigBird into Transformers. By doing so, you will both gain a 
+theoretical and deep practical understanding of BigBird. 
+But more importantly, you will have made a major
+open-source contribution to Transformers. Along the way, you will:
+
+-   get insights into open-source best practices
+-   understand the design principles of one of the most popular NLP
+    libraries
+-   learn how to do efficiently test large NLP models
+-   learn how to integrate Python utilities like `black`, `ruff`,
+    `make fix-copies` into a library to always ensure clean and readable
+    code
+
+To start, let's try to get a general overview of the Transformers
+library.
+
+General overview of 🤗 Transformers
+----------------------------------
+
+First, you should get a general overview of 🤗 Transformers. Transformers 
+is a very opinionated library, so there is a chance that
+you don't agree with some of the library's philosophies or design
+choices. From our experience, however, we found that the fundamental
+design choices and philosophies of the library are crucial to
+efficiently scale Transformers while keeping maintenance costs at a
+reasonable level.
+
+A good first starting point to better understand the library is to read
+the [documentation of our philosophy](https://huggingface.co/transformers/philosophy.html).
+As a result of our way of working, there are some choices that we try to apply to all models:
+
+-   Composition is generally favored over abstraction
+-   Duplicating code is not always bad if it strongly improves the
+    readability or accessibility of a model
+-   Model files are as self-contained as possible so that when you read
+    the code of a specific model, you ideally only have to look into the
+    respective `modeling_....py` file.
+
+In our opinion, the library's code is not just a means to provide a
+product, *e.g.*, the ability to use BERT for inference, but also as the
+very product that we want to improve. Hence, when adding a model, the
+user is not only the person that will use your model, but also everybody
+that will read, try to understand, and possibly tweak your code.
+
+With this in mind, let's go a bit deeper into the general library
+design.
+
+### Overview of models
+
+To successfully add a model, it is important to understand the
+interaction between your model and its config,
+`PreTrainedModel`, and `PretrainedConfig`. For
+exemplary purposes, we will call the PyTorch model to be added to 🤗 Transformers
+`BrandNewBert`.
+
+Let's take a look:
+
+![image](https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers_overview.png)
+
+As you can see, we do make use of inheritance in 🤗 Transformers, but we
+keep the level of abstraction to an absolute minimum. There are never
+more than two levels of abstraction for any model in the library.
+`BrandNewBertModel` inherits from
+`BrandNewBertPreTrainedModel` which in
+turn inherits from `PreTrainedModel` and that's it. 
+As a general rule, we want to make sure
+that a new model only depends on `PreTrainedModel`. The
+important functionalities that are automatically provided to every new
+model are
+`PreTrainedModel.from_pretrained` and `PreTrainedModel.save_pretrained`, which are 
+used for serialization and deserialization. All
+of the other important functionalities, such as
+`BrandNewBertModel.forward` should be
+completely defined in the new `modeling_brand_new_bert.py` module. Next,
+we want to make sure that a model with a specific head layer, such as
+`BrandNewBertForMaskedLM` does not inherit
+from `BrandNewBertModel`, but rather uses
+`BrandNewBertModel` as a component that
+can be called in its forward pass to keep the level of abstraction low.
+Every new model requires a configuration class, called
+`BrandNewBertConfig`. This configuration
+is always stored as an attribute in
+`PreTrainedModel`, and
+thus can be accessed via the `config` attribute for all classes
+inheriting from `BrandNewBertPreTrainedModel`
+
+```python
+# assuming that `brand_new_bert` belongs to the organization `brandy`
+model = BrandNewBertModel.from_pretrained("brandy/brand_new_bert")
+model.config  # model has access to its config
+```
+
+Similar to the model, the configuration inherits basic serialization and
+deserialization functionalities from
+`PretrainedConfig`. Note
+that the configuration and the model are always serialized into two
+different formats - the model to a `pytorch_model.bin` file
+and the configuration to a `config.json` file. Calling
+`PreTrainedModel.save_pretrained` will automatically call
+`PretrainedConfig.save_pretrained`, so that both model and configuration are saved.
+
+### Overview of tokenizers
+
+Not quite ready yet :-( This section will be added soon!
+
+Step-by-step recipe to add a model to 🤗 Transformers
+----------------------------------------------------
+
+Everyone has different preferences of how to port a model so it can be
+very helpful for you to take a look at summaries of how other
+contributors ported models to Hugging Face. Here is a list of community
+blog posts on how to port a model:
+
+1.  [Porting GPT2
+    Model](https://medium.com/huggingface/from-tensorflow-to-pytorch-265f40ef2a28)
+    by [Thomas](https://huggingface.co/thomwolf)
+2.  [Porting WMT19 MT Model](https://huggingface.co/blog/porting-fsmt)
+    by [Stas](https://huggingface.co/stas)
+
+From experience, we can tell you that the most important things to keep
+in mind when adding a model are:
+
+-   Don't reinvent the wheel! Most parts of the code you will add for
+    the new 🤗 Transformers model already exist somewhere in 🤗
+    Transformers. Take some time to find similar, already existing
+    models and tokenizers you can copy from.
+    [grep](https://www.gnu.org/software/grep/) and
+    [rg](https://github.com/BurntSushi/ripgrep) are your friends. Note
+    that it might very well happen that your model's tokenizer is based
+    on one model implementation, and your model's modeling code on
+    another one. *E.g.*, FSMT's modeling code is based on BART, while
+    FSMT's tokenizer code is based on XLM.
+-   It's more of an engineering challenge than a scientific challenge.
+    You should spend more time on creating an efficient debugging
+    environment than trying to understand all theoretical aspects of the
+    model in the paper.
+-   Ask for help when you're stuck! Models are the core component of 🤗
+    Transformers so we, at Hugging Face, are more than happy to help
+    you at every step to add your model. Don't hesitate to ask if you
+    notice you are not making progress.
+
+In the following, we try to give you a general recipe that we found most
+useful when porting a model to 🤗 Transformers.
+
+The following list is a summary of everything that has to be done to add
+a model and can be used by you as a To-Do List:
+
+1.  [ ] (Optional) Understood theoretical aspects
+
+2.  [ ] Prepared transformers dev environment
+
+3.  [ ] Set up debugging environment of the original repository
+
+4.  [ ] Created script that successfully runs forward pass using
+    original repository and checkpoint
+
+5.  [ ] Successfully opened a PR and added the model skeleton to Transformers
+
+6.  [ ] Successfully converted original checkpoint to Transformers
+    checkpoint
+
+7.  [ ] Successfully ran forward pass in Transformers that gives
+    identical output to original checkpoint
+
+8.  [ ] Finished model tests in Transformers
+
+9.  [ ] Successfully added Tokenizer in Transformers
+
+10. [ ] Run end-to-end integration tests
+
+11. [ ] Finished docs
+
+12. [ ] Uploaded model weights to the hub
+
+13. [ ] Submitted the pull request for review
+
+14. [ ] (Optional) Added a demo notebook
+
+To begin with, we usually recommend to start by getting a good
+theoretical understanding of `BigBird`. However, if you prefer to
+understand the theoretical aspects of the model *on-the-job*, then it is
+totally fine to directly dive into the `BigBird`'s code-base. This
+option might suit you better, if your engineering skills are better than
+your theoretical skill, if you have trouble understanding
+`BigBird`'s paper, or if you just enjoy programming much more than
+reading scientific papers.
+
+### 1. (Optional) Theoretical aspects of BigBird
+
+You should take some time to read *BigBird's* paper, if such
+descriptive work exists. There might be large sections of the paper that
+are difficult to understand. If this is the case, this is fine - don't
+worry! The goal is not to get a deep theoretical understanding of the
+paper, but to extract the necessary information required to effectively
+re-implement the model in 🤗 Transformers. That being said, you don't
+have to spend too much time on the theoretical aspects, but rather focus
+on the practical ones, namely:
+
+-   What type of model is *BigBird*? BERT-like encoder-only
+    model? GPT2-like decoder-only model? BART-like encoder-decoder
+    model? Look at the `model_summary` if
+    you're not familiar with the differences between those.
+-   What are the applications of *BigBird*? Text
+    classification? Text generation? Seq2Seq tasks, *e.g.,*
+    summarization?
+-   What is the novel feature of the model making it different from
+    BERT/GPT-2/BART?
+-   Which of the already existing [🤗 Transformers
+    models](https://huggingface.co/transformers/#contents) is most
+    similar to *BigBird*?
+-   What type of tokenizer is used? A sentencepiece tokenizer? Word
+    piece tokenizer? Is it the same tokenizer as used for BERT or BART?
+
+After you feel like you have gotten a good overview of the architecture
+of the model, you might want to write to Patrick with any
+questions you might have. This might include questions regarding the
+model's architecture, its attention layer, etc. We will be more than
+happy to help you.
+
+
+#### Additional resources
+
+ Before diving into the code, here are some additional resources that might be worth taking a look at:
+ 
+ - [Yannic Kilcher's paper summary](https://www.youtube.com/watch?v=WVPE62Gk3EM&ab_channel=YannicKilcher)
+ - [Yannic Kilcher's summary of Longformer](https://www.youtube.com/watch?v=_8KNb5iqblE&ab_channel=YannicKilcher) - Longformer and BigBird are **very** similar models. Since Longformer has already been ported to 🤗 Transformers, it is useful to understand the differences between the two models
+ - [Blog post](https://medium.com/dsc-msit/is-google-bigbird-gonna-be-the-new-leader-in-nlp-domain-8c95cecc30f8) - A relatively superficial blog post about BigBird. Might be a good starting point to understand BigBird
+
+#### Make sure you've understood the fundamental aspects of BigBird
+
+Alright, now you should be ready to take a closer look into the actual code of BigBird.
+You should have understood the following aspects of BigBird by now:
+
+- BigBird provides a new attention layer for long-range sequence modelling that can be used 
+  as a drop-in replacement for already existing architectures. This means that every transformer-based model architecture can replace its [Self-attention layer](https://towardsdatascience.com/illustrated-self-attention-2d627e33b20a) with BigBird's self-attention layer.
+- BigBird's self-attention layer is composed of three mechanisms: block sparse (local) self-attention, global self-attention, random self-attention
+- BigBird's block sparse (local) self-attention is different from Longformer's local self-attention. How so? Why does that matter? => Can be deployed on TPU much easier this way
+- BigBird can be implemented for both an encoder-only model **and** 
+  for an encoder-decoder model, which means that we can reuse lots of [code from RoBERTa](https://github.com/huggingface/transformers/blob/main/src/transformers/models/roberta/modeling_roberta.py) and [from PEGASUS](https://github.com/huggingface/transformers/blob/main/src/transformers/models/pegasus/modeling_pegasus.py) at a later stage.
+
+
+If any of the mentioned aspects above are **not** clear to you, now is a great time to talk to Patrick.
+
+### 2. Next prepare your environment
+
+1.  Fork the [repository](https://github.com/huggingface/transformers)
+    by clicking on the 'Fork' button on the repository's page. This
+    creates a copy of the code under your GitHub user account.
+
+2.  Clone your `transformers` fork to your local disk, and add the base
+    repository as a remote:
+
+    ```bash
+    git clone https://github.com/[your Github handle]/transformers.git
+    cd transformers
+    git remote add upstream https://github.com/huggingface/transformers.git
+    ```
+
+3.  Set up a development environment, for instance by running the
+    following command:
+
+    ```bash
+    python -m venv .env
+    source .env/bin/activate
+    pip install -e ".[dev]"
+    ```
+
+and return to the parent directory
+
+```bash
+cd ..
+```
+
+4.  We recommend adding the PyTorch version of *BigBird* to
+    Transformers. To install PyTorch, please follow the instructions [here](https://pytorch.org/get-started/locally/).
+
+**Note:** You don't need to have CUDA installed. Making the new model
+work on CPU is sufficient.
+
+5.  To port *BigBird*, you will also need access to its
+    original repository:
+
+```bash
+git clone https://github.com/google-research/bigbird.git 
+cd big_bird
+pip install -e .
+```
+
+Now you have set up a development environment to port *BigBird*
+to 🤗 Transformers.
+
+### Run a pretrained checkpoint using the original repository
+
+**3. Set up debugging environment**
+
+At first, you will work on the original *BigBird* repository.
+Often, the original implementation is very "researchy". Meaning that
+documentation might be lacking and the code can be difficult to
+understand. But this should be exactly your motivation to reimplement
+*BigBird*. At Hugging Face, one of our main goals is to *make
+people stand on the shoulders of giants* which translates here very well
+into taking a working model and rewriting it to make it as **accessible,
+user-friendly, and beautiful** as possible. This is the number-one
+motivation to re-implement models into 🤗 Transformers - trying to make
+complex new NLP technology accessible to **everybody**.
+
+You should start thereby by diving into the [original repository](https://github.com/google-research/bigbird).
+
+Successfully running the official pretrained model in the original
+repository is often **the most difficult** step. From our experience, it
+is very important to spend some time getting familiar with the original
+code-base. You need to figure out the following:
+
+-   Where to find the pretrained weights?
+-   How to load the pretrained weights into the corresponding model?
+-   How to run the tokenizer independently from the model?
+-   Trace one forward pass so that you know which classes and functions
+    are required for a simple forward pass. Usually, you only have to
+    reimplement those functions.
+-   Be able to locate the important components of the model: Where is
+    the model's class? Are there model sub-classes, *e.g.*,
+    EncoderModel, DecoderModel? Where is the self-attention layer? Are
+    there multiple different attention layers, *e.g.*, *self-attention*,
+    *cross-attention*...?
+-   How can you debug the model in the original environment of the repo?
+    Do you have to add `print` statements, can you work with
+    an interactive debugger like [ipdb](https://pypi.org/project/ipdb/), or should you use
+    an efficient IDE to debug the model, like PyCharm?
+
+It is very important that before you start the porting process, that you
+can **efficiently** debug code in the original repository! Also,
+remember that you are working with an open-source library, so do not
+hesitate to open an issue, or even a pull request in the original
+repository. The maintainers of this repository are most likely very
+happy about someone looking into their code!
+
+At this point, it is really up to you which debugging environment and
+strategy you prefer to use to debug the original model. We strongly
+advise against setting up a costly GPU environment, but simply work on a
+CPU both when starting to dive into the original repository and also
+when starting to write the 🤗 Transformers implementation of the model.
+Only at the very end, when the model has already been successfully
+ported to 🤗 Transformers, one should verify that the model also works as
+expected on GPU.
+
+In general, there are two possible debugging environments for running
+the original model
+
+-   [Jupyter notebooks](https://jupyter.org/) / [google colab](https://colab.research.google.com/notebooks/intro.ipynb)
+-   Local python scripts.
+
+Jupyter notebooks have the advantage that they allow for cell-by-cell
+execution which can be helpful to better split logical components from
+one another and to have faster debugging cycles as intermediate results
+can be stored. Also, notebooks are often easier to share with other
+contributors, which might be very helpful if you want to ask the Hugging
+Face team for help. If you are familiar with Jupyter notebooks, we
+strongly recommend you to work with them.
+
+The obvious disadvantage of Jupyter notebooks is that if you are not
+used to working with them you will have to spend some time adjusting to
+the new programming environment and that you might not be able to use
+your known debugging tools anymore, like `ipdb`.
+
+**4. Successfully run forward pass**
+
+For each code-base, a good first step is always to load a **small**
+pretrained checkpoint and to be able to reproduce a single forward pass
+using a dummy integer vector of input IDs as an input. Such a script
+could look something like this:
+
+```python
+from bigbird.core import modeling
+model = modeling.BertModel(bert_config)
+from bigbird.core import utils
+
+params = utils.BigBirdConfig(vocab_size=32000, hidden_size=512,
+    num_hidden_layers=8, num_attention_heads=6, intermediate_size=1024)
+
+ckpt_path = 'gs://bigbird-transformer/pretrain/bigbr_base/model.ckpt-0'
+ckpt_reader = tf.compat.v1.train.NewCheckpointReader(ckpt_path)
+model.set_weights([ckpt_reader.get_tensor(v.name[:-2]) for v in tqdm(model.trainable_weights, position=0)])
+
+input_ids = tf.constant([[31, 51, 99], [15, 5, 0]])
+_, pooled_output = model(input_ids=input_ids, token_type_ids=token_type_ids)
+...
+
+```
+
+Next, regarding the debugging strategy, there are generally a few from
+which to choose from:
+
+-   Decompose the original model into many small testable components and
+    run a forward pass on each of those for verification
+-   Decompose the original model only into the original *tokenizer* and
+    the original *model*, run a forward pass on those, and use
+    intermediate print statements or breakpoints for verification
+
+Again, it is up to you which strategy to choose. Often, one or the other
+is advantageous depending on the original code base.
+
+If the original code-base allows you to decompose the model into smaller
+sub-components, *e.g.*, if the original code-base can easily be run in
+eager mode, it is usually worth the effort to do so. There are some
+important advantages to taking the more difficult road in the beginning:
+
+-   at a later stage when comparing the original model to the Hugging
+    Face implementation, you can verify automatically for each component
+    individually that the corresponding component of the 🤗 Transformers
+    implementation matches instead of relying on visual comparison via
+    print statements
+-   it can give you some rope to decompose the big problem of porting a
+    model into smaller problems of just porting individual components
+    and thus structure your work better
+-   separating the model into logical meaningful components will help
+    you to get a better overview of the model's design and thus to
+    better understand the model
+-   at a later stage those component-by-component tests help you to
+    ensure that no regression occurs as you continue changing your code
+
+[Lysandre's](https://gist.github.com/LysandreJik/db4c948f6b4483960de5cbac598ad4ed)
+integration checks for ELECTRA gives a nice example of how this can be
+done.
+
+However, if the original code-base is very complex or only allows
+intermediate components to be run in a compiled mode, it might be too
+time-consuming or even impossible to separate the model into smaller
+testable sub-components. A good example is [T5's
+MeshTensorFlow](https://github.com/tensorflow/mesh/tree/master/mesh_tensorflow)
+library which is very complex and does not offer a simple way to
+decompose the model into its sub-components. For such libraries, one
+often relies on verifying print statements.
+
+No matter which strategy you choose, the recommended procedure is often
+the same in that you should start to debug the starting layers first and
+the ending layers last.
+
+It is recommended that you retrieve the output, either by print
+statements or sub-component functions, of the following layers in the
+following order:
+
+1.  Retrieve the input IDs passed to the model
+2.  Retrieve the word embeddings
+3.  Retrieve the input of the first Transformer layer
+4.  Retrieve the output of the first Transformer layer
+5.  Retrieve the output of the following n - 1 Transformer layers
+6.  Retrieve the output of the whole BigBird Model
+
+Input IDs should thereby consists of an array of integers, *e.g.*,
+`input_ids = [0, 4, 4, 3, 2, 4, 1, 7, 19]`
+
+The outputs of the following layers often consist of multi-dimensional
+float arrays and can look like this:
+
+```bash
+[[
+ [-0.1465, -0.6501,  0.1993,  ...,  0.1451,  0.3430,  0.6024],
+ [-0.4417, -0.5920,  0.3450,  ..., -0.3062,  0.6182,  0.7132],
+ [-0.5009, -0.7122,  0.4548,  ..., -0.3662,  0.6091,  0.7648],
+ ...,
+ [-0.5613, -0.6332,  0.4324,  ..., -0.3792,  0.7372,  0.9288],
+ [-0.5416, -0.6345,  0.4180,  ..., -0.3564,  0.6992,  0.9191],
+ [-0.5334, -0.6403,  0.4271,  ..., -0.3339,  0.6533,  0.8694]]],
+```
+
+We expect that every model added to 🤗 Transformers passes a couple of
+integration tests, meaning that the original model and the reimplemented
+version in 🤗 Transformers have to give the exact same output up to a
+precision of 0.001! Since it is normal that the exact same model written
+in different libraries can give a slightly different output depending on
+the library framework, we accept an error tolerance of 1e-3 (0.001). It
+is not enough if the model gives nearly the same output, they have to be
+the almost identical. Therefore, you will certainly compare the
+intermediate outputs of the 🤗 Transformers version multiple times
+against the intermediate outputs of the original implementation of
+*BigBird* in which case an **efficient** debugging environment
+of the original repository is absolutely important. Here is some advice
+to make your debugging environment as efficient as possible.
+
+-   Find the best way of debugging intermediate results. Is the original
+    repository written in PyTorch? Then you should probably take the
+    time to write a longer script that decomposes the original model
+    into smaller sub-components to retrieve intermediate values. Is the
+    original repository written in Tensorflow 1? Then you might have to
+    rely on TensorFlow print operations like
+    [tf.print](https://www.tensorflow.org/api_docs/python/tf/print) to
+    output intermediate values. Is the original repository written in
+    Jax? Then make sure that the model is **not jitted** when running
+    the forward pass, *e.g.*, check-out [this
+    link](https://github.com/google/jax/issues/196).
+-   Use the smallest pretrained checkpoint you can find. The smaller the
+    checkpoint, the faster your debug cycle becomes. It is not efficient
+    if your pretrained model is so big that your forward pass takes more
+    than 10 seconds. In case only very large checkpoints are available,
+    it might make more sense to create a dummy model in the new
+    environment with randomly initialized weights and save those weights
+    for comparison with the 🤗 Transformers version of your model
+-   Make sure you are using the easiest way of calling a forward pass in
+    the original repository. Ideally, you want to find the function in
+    the original repository that **only** calls a single forward pass,
+    *i.e.* that is often called `predict`, `evaluate`, `forward` or
+    `__call__`. You don't want to debug a function that calls `forward`
+    multiple times, *e.g.*, to generate text, like
+    `autoregressive_sample`, `generate`.
+-   Try to separate the tokenization from the model's
+    forward pass. If the original repository shows
+    examples where you have to input a string, then try to find out
+    where in the forward call the string input is changed to input ids
+    and start from this point. This might mean that you have to possibly
+    write a small script yourself or change the original code so that
+    you can directly input the ids instead of an input string.
+-   Make sure that the model in your debugging setup is **not** in
+    training mode, which often causes the model to yield random outputs
+    due to multiple dropout layers in the model. Make sure that the
+    forward pass in your debugging environment is **deterministic** so
+    that the dropout layers are not used. Or use
+    `transformers.utils.set_seed` if the old and new
+    implementations are in the same framework.
+
+#### (Important) More details on how to create a debugging environment for BigBird 
+
+- BigBird has multiple pretrained checkpoints that should eventually all be ported to 
+  🤗 Transformers. The pretrained checkpoints can be found [here](https://console.cloud.google.com/storage/browser/bigbird-transformer/pretrain;tab=objects?prefix=&forceOnObjectsSortingFiltering=false). 
+	Those checkpoints include both pretrained weights for encoder-only (BERT/RoBERTa) under the folder `bigbr_base` and encoder-decoder (PEGASUS) under the folder `bigbp_large`.
+	You should start by porting the `bigbr_base` model. The encoder-decoder model 
+	can be ported afterward.
+	for an encoder-decoder architecture as well as an encoder-only architecture. 
+- BigBird was written in tf.compat meaning that a mixture of a TensorFlow 1 and 
+  TensorFlow 2 API was used.
+- The most important part of the BigBird code-base is [bigbird.bigbird.core](https://github.com/google-research/bigbird/tree/master/bigbird/core) which includes all logic necessary 
+  to implement BigBird.
+- The first goal should be to successfully run a forward pass using the RoBERTa checkpoint `bigbr_base/model.ckpt-0.data-00000-of-00001` and `bigbr_base/model.ckpt-0.index`.
+
+
+### Port BigBird to 🤗 Transformers
+
+Next, you can finally start adding new code to 🤗 Transformers. Go into
+the clone of your 🤗 Transformers' fork:
+
+    cd transformers
+
+In the special case that you are adding a model whose architecture
+exactly matches the model architecture of an existing model you only
+have to add a conversion script as described in [this
+section](#write-a-conversion-script). In this case, you can just re-use
+the whole model architecture of the already existing model.
+
+Otherwise, let's start generating a new model with the amazing
+Cookiecutter!
+
+**Use the Cookiecutter to automatically generate the model's code**
+
+To begin with head over to the [🤗 Transformers
+templates](https://github.com/huggingface/transformers/tree/main/templates/adding_a_new_model)
+to make use of our `cookiecutter` implementation to automatically
+generate all the relevant files for your model. Again, we recommend only
+adding the PyTorch version of the model at first. Make sure you follow
+the instructions of the `README.md` on the [🤗 Transformers
+templates](https://github.com/huggingface/transformers/tree/main/templates/adding_a_new_model)
+carefully.
+Since you will first implement the Encoder-only/RoBERTa-like version of BigBird you should 
+select the `is_encoder_decoder_model = False` option in the cookiecutter. Also, it is recommended
+that you implement the model only in PyTorch in the beginning and select "Standalone" as the 
+tokenizer type for now.
+
+**Open a Pull Request on the main huggingface/transformers repo**
+
+Before starting to adapt the automatically generated code, now is the
+time to open a "Work in progress (WIP)" pull request, *e.g.*, "\[WIP\]
+Add *BigBird*", in 🤗 Transformers so that you and the Hugging
+Face team can work side-by-side on integrating the model into 🤗
+Transformers.
+
+You should do the following:
+
+1.  Create a branch with a descriptive name from your main branch
+
+```bash
+    git checkout -b add_big_bird
+```
+
+2.  Commit the automatically generated code:
+
+```bash
+    git add .
+    git commit
+```
+
+3.  Fetch and rebase to current main
+
+```bash
+    git fetch upstream
+    git rebase upstream/main
+```
+
+4.  Push the changes to your account using:
+
+```bash
+    git push -u origin a-descriptive-name-for-my-changes
+```
+
+5.  Once you are satisfied, go to the webpage of your fork on GitHub.
+    Click on "Pull request". Make sure to add the GitHub handle of Patrick 
+		as one reviewer, so that the Hugging Face team gets notified for future changes.
+
+6.  Change the PR into a draft by clicking on "Convert to draft" on the
+    right of the GitHub pull request web page.
+
+In the following, whenever you have done some progress, don't forget to
+commit your work and push it to your account so that it shows in the
+pull request. Additionally, you should make sure to update your work
+with the current main from time to time by doing:
+
+    git fetch upstream
+    git merge upstream/main
+
+In general, all questions you might have regarding the model or your
+implementation should be asked in your PR and discussed/solved in the
+PR. This way, Patrick will always be notified when you are
+committing new code or if you have a question. It is often very helpful
+to point Patrick to your added code so that the Hugging
+Face team can efficiently understand your problem or question.
+
+To do so, you can go to the "Files changed" tab where you see all of
+your changes, go to a line regarding which you want to ask a question,
+and click on the "+" symbol to add a comment. Whenever a question or
+problem has been solved, you can click on the "Resolve" button of the
+created comment.
+
+In the same way, Patrick will open comments when reviewing
+your code. We recommend asking most questions on GitHub on your PR. For
+some very general questions that are not very useful for the public,
+feel free to ping Patrick by Slack or email.
+
+**5. Adapt the generated models code for BigBird**
+
+At first, we will focus only on the model itself and not care about the
+tokenizer. All the relevant code should be found in the generated files
+`src/transformers/models/big_bird/modeling_big_bird.py` and
+`src/transformers/models/big_bird/configuration_big_bird.py`.
+
+Now you can finally start coding :). The generated code in
+`src/transformers/models/big_bird/modeling_big_bird.py` will
+either have the same architecture as BERT if it's an encoder-only model
+or BART if it's an encoder-decoder model. At this point, you should
+remind yourself what you've learned in the beginning about the
+theoretical aspects of the model: *How is the model different from BERT
+or BART?*\". Implement those changes which often means to change the
+*self-attention* layer, the order of the normalization layer, etc...
+Again, it is often useful to look at the similar architecture of already
+existing models in Transformers to get a better feeling of how your
+model should be implemented.
+
+**Note** that at this point, you don't have to be very sure that your
+code is fully correct or clean. Rather, it is advised to add a first
+*unclean*, copy-pasted version of the original code to
+`src/transformers/models/big_bird/modeling_big_bird.py`
+until you feel like all the necessary code is added. From our
+experience, it is much more efficient to quickly add a first version of
+the required code and improve/correct the code iteratively with the
+conversion script as described in the next section. The only thing that
+has to work at this point is that you can instantiate the 🤗 Transformers
+implementation of *BigBird*, *i.e.* the following command
+should work:
+
+```python
+from transformers import BigBirdModel, BigBirdConfig
+model = BigBirdModel(BigBirdConfig())
+```
+
+The above command will create a model according to the default
+parameters as defined in `BigBirdConfig()` with random weights,
+thus making sure that the `init()` methods of all components works.
+
+Note that for BigBird you have to change the attention layer. BigBird's attention
+layer is quite complex as you can see [here](https://github.com/google-research/bigbird/blob/103a3345f94bf6364749b51189ed93024ca5ef26/bigbird/core/attention.py#L560). Don't 
+feel discouraged by this! In a first step you should simply make sure that 
+the layer `BigBirdAttention` has the correct weights as can be found in the 
+pretrained checkpoints. This means that you have to make sure that in the 
+`__init__(self, ...)` function of `BigBirdAttention`, all submodules include all 
+necessary `nn.Module` layers. Only at a later stage do we need to fully rewrite 
+the complex attention function.
+
+**6. Write a conversion script**
+
+Next, you should write a conversion script that lets you convert the
+checkpoint you used to debug *BigBird* in the original
+repository to a checkpoint compatible with your just created 🤗
+Transformers implementation of *BigBird*. It is not advised to
+write the conversion script from scratch, but rather to look through
+already existing conversion scripts in 🤗 Transformers for one that has
+been used to convert a similar model that was written in the same
+framework as *BigBird*. Usually, it is enough to copy an
+already existing conversion script and slightly adapt it for your use
+case. Don't hesitate to ask Patrick to point you to a
+similar already existing conversion script for your model.
+
+-   A good starting point to convert the original TF BigBird implementation to the PT Hugging Face implementation is probably BERT's conversion script
+    [here](https://github.com/huggingface/transformers/blob/7acfa95afb8194f8f9c1f4d2c6028224dbed35a2/src/transformers/models/bert/modeling_bert.py#L91)
+
+You can copy paste the conversion function into `modeling_big_bird.py` and then adapt it 
+to your needs.
+
+In the following, we'll quickly explain how PyTorch models store layer
+weights and define layer names. In PyTorch, the name of a layer is
+defined by the name of the class attribute you give the layer. Let's
+define a dummy model in PyTorch, called `SimpleModel` as follows:
+
+```python
+from torch import nn
+
+class SimpleModel(nn.Module):
+    def __init__(self):
+            super().__init__()
+            self.dense = nn.Linear(10, 10)
+            self.intermediate = nn.Linear(10, 10)
+            self.layer_norm = nn.LayerNorm(10)
+```
+
+Now we can create an instance of this model definition which will fill
+all weights: `dense`, `intermediate`, `layer_norm` with random weights.
+We can print the model to see its architecture
+
+```python
+model = SimpleModel()
+
+print(model)
+```
+
+This will print out the following:
+
+```bash
+SimpleModel(
+  (dense): Linear(in_features=10, out_features=10, bias=True)
+  (intermediate): Linear(in_features=10, out_features=10, bias=True)
+  (layer_norm): LayerNorm((10,), eps=1e-05, elementwise_affine=True)
+)
+```
+
+We can see that the layer names are defined by the name of the class
+attribute in PyTorch. You can print out the weight values of a specific
+layer:
+
+```python
+print(model.dense.weight.data)
+```
+
+to see that the weights were randomly initialized
+
+```bash
+tensor([[-0.0818,  0.2207, -0.0749, -0.0030,  0.0045, -0.1569, -0.1598,  0.0212,

+         -0.1023, -0.0447],
+        [-0.0888, -0.1092,  0.2281,  0.0336,  0.1817, -0.0115,  0.2096,  0.1415,
+         -0.1876, -0.2467],
+        [ 0.2208, -0.2352, -0.1426, -0.2636, -0.2889, -0.2061, -0.2849, -0.0465,
+          0.2577,  0.0402],
+        [ 0.1502,  0.2465,  0.2566,  0.0693,  0.2352, -0.0530,  0.1859, -0.0604,
+          0.2132,  0.1680],
+        [ 0.1733, -0.2407, -0.1721,  0.1484,  0.0358, -0.0633, -0.0721, -0.0090,
+          0.2707, -0.2509],
+        [-0.1173,  0.1561,  0.2945,  0.0595, -0.1996,  0.2988, -0.0802,  0.0407,
+          0.1829, -0.1568],
+        [-0.1164, -0.2228, -0.0403,  0.0428,  0.1339,  0.0047,  0.1967,  0.2923,
+          0.0333, -0.0536],
+        [-0.1492, -0.1616,  0.1057,  0.1950, -0.2807, -0.2710, -0.1586,  0.0739,
+          0.2220,  0.2358]]).
+```
+
+In the conversion script, you should fill those randomly initialized
+weights with the exact weights of the corresponding layer in the
+checkpoint. *E.g.*,
+
+```python
+# retrieve matching layer weights, e.g. by 
+# recursive algorithm
+layer_name = "dense"
+pretrained_weight = array_of_dense_layer
+
+model_pointer = getattr(model, "dense")
+
+model_pointer.weight.data = torch.from_numpy(pretrained_weight)
+```
+
+While doing so, you must verify that each randomly initialized weight of
+your PyTorch model and its corresponding pretrained checkpoint weight
+exactly match in both **shape and name**. To do so, it is **necessary**
+to add assert statements for the shape and print out the names of the
+checkpoints weights. *E.g.*, you should add statements like:
+
+```python
+assert (
+     model_pointer.weight.shape == pretrained_weight.shape
+), f"Pointer shape of random weight {model_pointer.shape} and array shape of checkpoint weight {pretrained_weight.shape} mismatched"
+```
+
+Besides, you should also print out the names of both weights to make
+sure they match, *e.g.*,
+
+```python
+logger.info(f"Initialize PyTorch weight {layer_name} from {pretrained_weight.name}")
+```
+
+If either the shape or the name doesn't match, you probably assigned
+the wrong checkpoint weight to a randomly initialized layer of the 🤗
+Transformers implementation.
+
+An incorrect shape is most likely due to an incorrect setting of the
+config parameters in `BigBirdConfig()` that do not exactly match
+those that were used for the checkpoint you want to convert. However, it
+could also be that PyTorch's implementation of a layer requires the
+weight to be transposed beforehand.
+
+Finally, you should also check that **all** required weights are
+initialized and print out all checkpoint weights that were not used for
+initialization to make sure the model is correctly converted. It is
+completely normal, that the conversion trials fail with either a wrong
+shape statement or wrong name assignment. This is most likely because
+either you used incorrect parameters in `BigBirdConfig()`, have a
+wrong architecture in the 🤗 Transformers implementation, you have a bug
+in the `init()` functions of one of the components of the 🤗 Transformers
+implementation or you need to transpose one of the checkpoint weights.
+
+This step should be iterated with the previous step until all weights of
+the checkpoint are correctly loaded in the Transformers model. Having
+correctly loaded the checkpoint into the 🤗 Transformers implementation,
+you can then save the model under a folder of your choice
+`/path/to/converted/checkpoint/folder` that should then contain both a
+`pytorch_model.bin` file and a `config.json` file:
+
+```python
+model.save_pretrained("/path/to/converted/checkpoint/folder")
+```
+
+**7. Implement the forward pass**
+
+Having managed to correctly load the pretrained weights into the 🤗
+Transformers implementation, you should now make sure that the forward
+pass is correctly implemented. In [Get familiar with the original
+repository](#run-a-pretrained-checkpoint-using-the-original-repository),
+you have already created a script that runs a forward pass of the model
+using the original repository. Now you should write an analogous script
+using the 🤗 Transformers implementation instead of the original one. It
+should look as follows:
+
+[Here the model name might have to be adapted, *e.g.*, maybe BigBirdForConditionalGeneration instead of BigBirdModel]
+
+```python
+model = BigBirdModel.from_pretrained("/path/to/converted/checkpoint/folder")
+input_ids = [0, 4, 4, 3, 2, 4, 1, 7, 19]
+output = model(input_ids).last_hidden_states
+```
+
+It is very likely that the 🤗 Transformers implementation and the
+original model implementation don't give the exact same output the very
+first time or that the forward pass throws an error. Don't be
+disappointed - it's expected! First, you should make sure that the
+forward pass doesn't throw any errors. It often happens that the wrong
+dimensions are used leading to a `"Dimensionality mismatch"`
+error or that the wrong data type object is used, *e.g.*, `torch.long`
+instead of `torch.float32`. Don't hesitate to ask Patrick
+for help, if you don't manage to solve certain errors.
+
+The final part to make sure the 🤗 Transformers implementation works
+correctly is to ensure that the outputs are equivalent to a precision of
+`1e-3`. First, you should ensure that the output shapes are identical,
+*i.e.* `outputs.shape` should yield the same value for the script of the
+🤗 Transformers implementation and the original implementation. Next, you
+should make sure that the output values are identical as well. This one
+of the most difficult parts of adding a new model. Common mistakes why
+the outputs are not identical are:
+
+-   Some layers were not added, *i.e.* an activation layer
+    was not added, or the residual connection was forgotten
+-   The word embedding matrix was not tied
+-   The wrong positional embeddings are used because the original
+    implementation uses on offset
+-   Dropout is applied during the forward pass. To fix this make sure
+    `model.training is False` and that no dropout layer is
+    falsely activated during the forward pass, *i.e.* pass
+    `self.training` to [PyTorch's functional
+    dropout](https://pytorch.org/docs/stable/nn.functional.html?highlight=dropout#torch.nn.functional.dropout)
+
+The best way to fix the problem is usually to look at the forward pass
+of the original implementation and the 🤗 Transformers implementation
+side-by-side and check if there are any differences. Ideally, you should
+debug/print out intermediate outputs of both implementations of the
+forward pass to find the exact position in the network where the 🤗
+Transformers implementation shows a different output than the original
+implementation. First, make sure that the hard-coded `input_ids` in both
+scripts are identical. Next, verify that the outputs of the first
+transformation of the `input_ids` (usually the word embeddings) are
+identical. And then work your way up to the very last layer of the
+network. At some point, you will notice a difference between the two
+implementations, which should point you to the bug in the 🤗 Transformers
+implementation. From our experience, a simple and efficient way is to
+add many print statements in both the original implementation and 🤗
+Transformers implementation, at the same positions in the network
+respectively, and to successively remove print statements showing the
+same values for intermediate presentions.
+
+When you're confident that both implementations yield the same output,
+verifying the outputs with
+`torch.allclose(original_output, output, atol=1e-3)`, you're done with
+the most difficult part! Congratulations - the work left to be done
+should be a cakewalk 😊.
+
+**8. Adding all necessary model tests**
+
+At this point, you have successfully added a new model. However, it is
+very much possible that the model does not yet fully comply with the
+required design. To make sure, the implementation is fully compatible
+with 🤗 Transformers, all common tests should pass. The Cookiecutter
+should have automatically added a test file for your model, probably
+under the same `tests/test_modeling_big_bird.py`. Run this test
+file to verify that all common tests pass:
+
+```python
+pytest tests/test_modeling_big_bird.py
+```
+
+Having fixed all common tests, it is now crucial to ensure that all the
+nice work you have done is well tested, so that
+
+-   a)  The community can easily understand your work by looking at
+        specific tests of *BigBird*
+
+-   b)  Future changes to your model will not break any important
+        feature of the model.
+
+At first, integration tests should be added. Those integration tests
+essentially do the same as the debugging scripts you used earlier to
+implement the model to 🤗 Transformers. A template of those model tests
+is already added by the Cookiecutter, called
+`BigBirdModelIntegrationTests` and only has to be filled out by
+you. To ensure that those tests are passing, run
+
+```python
+RUN_SLOW=1 pytest -sv tests/test_modeling_big_bird.py::BigBirdModelIntegrationTests
+```
+
+**Note**: In case you are using Windows, you should replace `RUN_SLOW=1` with
+`SET RUN_SLOW=1`
+
+Second, all features that are special to *BigBird* should be
+tested additionally in a separate test under
+`BigBirdModelTester`/`BigBirdModelTest`. This part is often
+forgotten but is extremely useful in two ways:
+
+-   It helps to transfer the knowledge you have acquired during the
+    model addition to the community by showing how the special features
+    of *BigBird* should work.
+-   Future contributors can quickly test changes to the model by running
+    those special tests.
+
+BigBird has quite a complex attention layer, so it is very important 
+to add more tests verifying the all parts of BigBird's self-attention layer 
+works as expected. This means that there should be at least 3 additional tests:
+
+- 1. Verify that the sparse attention works correctly
+- 2. Verify that the global attention works correctly
+- 3. Verify that the random attention works correctly
+
+**9. Implement the tokenizer**
+
+Next, we should add the tokenizer of *BigBird*. Usually, the
+tokenizer is equivalent or very similar to an already existing tokenizer
+of 🤗 Transformers.
+
+In the case of BigBird you should be able to just rely on an already existing tokenizer.
+If not mistaken, BigBird uses the same tokenizer that was used for `BertGenerationTokenizer`,
+which is based on `sentencepiece`. So you should be able to just set the config parameter 
+`tokenizer_class` to `BertGenerationTokenizer` without having to implement any new tokenizer.
+
+It is very important to find/extract the original tokenizer file and to
+manage to load this file into the 🤗 Transformers' implementation of the
+tokenizer.
+
+For BigBird, the tokenizer (sentencepiece) files can be found [here](https://github.com/google-research/bigbird/blob/master/bigbird/vocab/gpt2.model), which you should be able to load 
+as easily as:
+
+```python
+from transformers import BertGenerationTokenizer
+tokenizer = BertGenerationTokenizer("/path/to/gpt2.model/file")
+```
+
+To ensure that the tokenizer works correctly, it is recommended to first
+create a script in the original repository that inputs a string and
+returns the `input_ids`. It could look similar to this (in pseudo-code):
+
+```bash
+input_str = "This is a long example input string containing special characters .$?-, numbers 2872 234 12 and words."
+model = BigBirdModel.load_pretrained_checkpoint("/path/to/checkpoint/")
+input_ids = model.tokenize(input_str)
+```
+
+You might have to take a deeper look again into the original repository
+to find the correct tokenizer function or you might even have to do
+changes to your clone of the original repository to only output the
+`input_ids`. Having written a functional tokenization script that uses
+the original repository, an analogous script for 🤗 Transformers should
+be created. It should look similar to this:
+
+```python
+from transformers import BertGenerationTokenizer
+input_str = "This is a long example input string containing special characters .$?-, numbers 2872 234 12 and words."
+
+tokenizer = BertGenerationTokenizer.from_pretrained("/path/big/bird/folder")
+
+input_ids = tokenizer(input_str).input_ids
+```
+
+When both `input_ids` yield the same values, as a final step a tokenizer
+test file should also be added.
+
+Since BigBird is most likely fully based on `BertGenerationTokenizer`, 
+you should only add a couple of "slow" integration tests. However, in this 
+case you do **not** need to add any `BigBirdTokenizationTest`.
+
+**10. Run End-to-end integration tests**
+
+Having added the tokenizer, you should also add a couple of end-to-end
+integration tests using both the model and the tokenizer to
+`tests/test_modeling_big_bird.py` in 🤗 Transformers. Such a test
+should show on a meaningful text-to-text sample that the 🤗 Transformers
+implementation works as expected. A meaningful text-to-text sample can
+include, *e.g.*, a source-to-target-translation pair, an
+article-to-summary pair, a question-to-answer pair, etc... If none of
+the ported checkpoints has been fine-tuned on a downstream task it is
+enough to simply rely on the model tests. In a final step to ensure that
+the model is fully functional, it is advised that you also run all tests
+on GPU. It can happen that you forgot to add some `.to(self.device)`
+statements to internal tensors of the model, which in such a test would
+show in an error. In case you have no access to a GPU, the Hugging Face
+team can take care of running those tests for you.
+
+**11. Add Docstring**
+
+Now, all the necessary functionality for *BigBird* is added -
+you're almost done! The only thing left to add is a nice docstring and
+a doc page. The Cookiecutter should have added a template file called
+`docs/source/model_doc/big_bird.rst` that you should fill out.
+Users of your model will usually first look at this page before using
+your model. Hence, the documentation must be understandable and concise.
+It is very useful for the community to add some *Tips* to show how the
+model should be used. Don't hesitate to ping Patrick
+regarding the docstrings.
+
+Next, make sure that the docstring added to
+`src/transformers/models/big_bird/modeling_big_bird.py` is
+correct and included all necessary inputs and outputs. It is always to
+good to remind oneself that documentation should be treated at least as
+carefully as the code in 🤗 Transformers since the documentation is
+usually the first contact point of the community with the model.
+
+**Code refactor**
+
+Great, now you have added all the necessary code for *BigBird*.
+At this point, you should correct some potential incorrect code style by
+running:
+
+```bash
+make style
+```
+
+and verify that your coding style passes the quality check:
+
+```bash
+make quality
+```
+
+There are a couple of other very strict design tests in 🤗 Transformers
+that might still be failing, which shows up in the tests of your pull
+request. This is often because of some missing information in the
+docstring or some incorrect naming. Patrick will surely
+help you if you're stuck here.
+
+Lastly, it is always a good idea to refactor one's code after having
+ensured that the code works correctly. With all tests passing, now it's
+a good time to go over the added code again and do some refactoring.
+
+You have now finished the coding part, congratulation! 🎉 You are
+Awesome! 😎
+
+**12. Upload the models to the model hub**
+
+In this final part, you should convert and upload all checkpoints to the
+model hub and add a model card for each uploaded model checkpoint. You
+should work alongside Patrick here to decide on a fitting
+name for each checkpoint and to get the required access rights to be
+able to upload the model under the author's organization of
+*BigBird*.
+
+It is worth spending some time to create fitting model cards for each
+checkpoint. The model cards should highlight the specific
+characteristics of this particular checkpoint, *e.g.*, On which dataset
+was the checkpoint pretrained/fine-tuned on? On what down-stream task
+should the model be used? And also include some code on how to correctly
+use the model.
+
+**13. (Optional) Add notebook**
+
+It is very helpful to add a notebook that showcases in-detail how
+*BigBird* can be used for inference and/or fine-tuned on a
+downstream task. This is not mandatory to merge your PR, but very useful
+for the community.
+
+**14. Submit your finished PR**
+
+You're done programming now and can move to the last step, which is
+getting your PR merged into main. Usually, Patrick
+should have helped you already at this point, but it is worth taking
+some time to give your finished PR a nice description and eventually add
+comments to your code, if you want to point out certain design choices
+to your reviewer.
+
+### Share your work!!
+
+Now, it's time to get some credit from the community for your work!
+Having completed a model addition is a major contribution to
+Transformers and the whole NLP community. Your code and the ported
+pre-trained models will certainly be used by hundreds and possibly even
+thousands of developers and researchers. You should be proud of your
+work and share your achievement with the community.
+
+**You have made another model that is super easy to access for everyone
